I can't believe how much quality information is being put out by hobbyists like yourself. I just want to make sure that you know that it's greatly appreciated.
That whole pre-esprit series was phenomenal. I was a tech at a Sony authorized service center when they came out and remember going to the weekend training seminar in Chicago. I still have all the "New circuit design" manuals. It was all miles ahead of everything else in every detail. Pure artwork in engineering. It's as if they sat the engineers down and said, "If money were no object...."
I've been doing this as a hobby now for around 5 years. I am an electrician so not a newbie to electricity and circuits but diving into vintage pieces has become completely addictive. I really like your approaches and thought processes. Pretty much binged all your vids once I found you so kudos for all your work and thanks for sharing your talents
Hey Chris,,your vids are by far the most informative and easy to follow for novices like me.,Ive watched you for a few years now and commend you on the service and knowledge you provide,,Good Luck for the future from Ireland and keep the great knowledge coming, Thank You,
Excellent, on top of outstanding! First thing I noticed was there were no Tone controls. Why? You always give a perspective on how to approach these units.. Look first before you plug it in. Before I started with computers, audio was my forte. Thank you for your videos. They have helped me on how to service some old units I have. Please keep it up!
Another great Sony preamp was the later TA-E80ES from 1990. Those switches are gone 👍and back are tone controls, with selectable turnover, in a completely passive tone circuit that can be bypassed through source direct. Useful subsonic filter, balanced in and out, three tape loops and a separate processor loop. Best included MC phono stage I’ve heard, better than my Luxman L-590, but the use of a moving coil step up transformer is always better - quieter. It looks to be much easier to work on than the ‘88 if ever it becomes necessary. Mine still works perfectly after 32 years. Good luck, good health and thanks for all you do!
Greetings from North London, thanks for all the hard work.I really appreciate your channel. I do think at times people don't appreciate how much time and effort goes into making a RUclips channel like yours. Thank you.
Thank you so much for your kind words. I certainly have much more appreciation for movies, television shows, commercials and as you mentioned RUclips video's. I spend a lot of time on the video's but it keeps me and my mind busy. The video editing has become as much of a hobby as the vintage audio equipment. Thank you again for noticing. Cheers from the USA.
@@vintageaudioaddict I work with people with special needs, I'm also interested in hifi, music and film. I find that channels like yours and others that I follow it's my way of relaxing and when I tell people at work this, I get some funny looks, but I'm the first person they come to if they need any advice.
That Volume Switch look's like the precursor of the Mazda Wankel Engine. This reminds me of a quote: "In many ways, knowledge is easy to acquire; but imagination takes bravery and persistence". Keep these Restorations going!!!!
This is excellent Chris. Wow. The detail you provide here is great. And the production of your video is also first class. Wow. I know I’ve left this comment on your videos before, but I wish you were my neighbor, so you can help me repair my vintage audio equipment!!! Thanks again for these videos, Chris. Cheers! Jon
Man I can’t express how much I am enjoying your videos!! The attention to details and desire to teach others is simply awesome.. Been subscriber for a while but had not looked at more than a couple videos, but after getting into some vintage Marantz and Pioneer units and not having any local repair shops in my area, I remembered your channel.. Today I spent 6 hours watching or better states listening while driving down from College Station after buying some vintage JBLs. Now I am on the hunt for the equipment you referenced so I can start tinkering around!!’ Will be watching and learning !! Keep up the great work!!
Having a thought here. It’s probably wrong, but who knows. Is it possible to run a signal through a potentiometer and into an oscilloscope before de-oxidizing and note the wave form? The deox it and test it again to see if it’s fixed? It would save the pain of reassembling and finding out you didn't fix it. Just a thought.
Well.....Probably not. The controls can be so flakey. It would be hard to see on a scope unless the control was really bad. 95% of the time if you clean the control properly you'll be good to go.
i have no reasons to complain but i bought a sony integrated amplifier in the 70´s and it worked ok but in a matter of maybe 8 years i started to have problems while pioneer and technics components are all working today ,the Pioneers work without ever opening them since 1976 and a receiver from the ES-2000 system that had better finishings than the componets of that year catalog ,it was a receiver ,a turntable and a pair of speakers looking very good at the time, i still use it in my tv room having the matrix 4 option with two extra pair of celestion ditton and not even changed the wires or cables of each component in this system, all working from original maybe i´ll change the speaker cables this summer but i bought it in Japan so i wanted to keep it all original because it´s all written in japanese ,even the instruction inside a plastic cover atatched to the card box are in japanese and written in the perpendicular it´s a long sheet of paper, some years ago i paid 7€ for the brochure with photos and written in english for the first time i ever saw it, this from Ireland on Ebay
Great approach in these latest videos Chris. I loved the Pioneer promo video as I have started collecting vintage stuff myself since my cousin passed a Blue series stack system to me to take over the payments in 1980 as he couldn't afford the hp payments. Apart from the speakers (rotted away) & some slippy belts on the cassette deck it works perfectly well (although I know I should replace the caps). Started collecting after Pioneer taken over by Sounds United... I have cleaned & checked the pots switches & removed any dirt/flux but haven't built up the nerve to strip the SA508 amp caps out yet... Always check new gear as you suggest & remove old dirrt congealed coffee (in 656 mk2) flux etc & spray with WD40 contact cleaner - they've run cooler in every case so far... Used to make effects pedals for elec guitar in the 70"s when transistors had their own socket mounts they were so expensive! Many thanks for the videos - so informative & inspiring & getting me restarted! soldering again! Cheers from Portugal
Hi Andy, Greetings from the USA. Thank you so much for sharing your experiences. I'm glad that you have found the video's helpful. With you having past electronics experience I'm sure that any project you take on will be a success.
I have a question: Are the Rubicon capacitors a good choice for recap the Sony TA-E88? They have replaced them with 63v 1000mf and they are black :). Thanks for your time!
I love your videos. You have truly inspired me to delve into this hobby as I too share your love of vintage audio equipment and remember going to hi fi stores just to see all of the great equipment that was available back then. I have a question about choosing caps. I know you said it may be good to go up in voltage when choosing a replacement. is there a limit on how much you should increase the rated voltage? Also, can you increase the capacitance or should that remain to what the original cap is? Thank You for all you do.
Kent, thank you so much for the kind words and for watching. As far as the capacitance goes you should almost always stay with the same value as the original capacitor. The engineers who designed the equipment probably know best. With voltage there really are no issues with maximum voltage rating of capacitors being greater then the originals in vintage audio equipment.
I just can’t get enough of your videos, the content and detail of the restorations are priceless and I am learning a lot from you. Thank you for sharing your knowledge and your willingness to show the details and workflows. This content is just amazing and priceless
@@vintageaudioaddict a previous 'technician' destroyed the tuner mechanism.. its still broken. then had a no sound problem, it was the rear pre out switch.
First time on your channel and the cap speech you gave felt like a voice in my head. It's what I've been trying to explain to people since I service electronics, not just audio gear. I've never had any issues using chinese capacitors on any audio equipment and so far no customer has ever complained..Since I'm a little an audiophile myself I've never noticed any difference . I think it's a placebo... No matter the brand I will always trust a new cap more then the old, dried one, no matter where they make them as long as they're reliable...
@@vintageaudioaddict I'm currently working on a Technics SU-Z22 integrated amp from 1981 that was so neglected that I almost gave up but now I'm glad I didn't... Very rich sound from STK 2038...
I own a siglent SDG 1032X Arbitrary waveform generator. It's suppoda be good for up to 35MHz. So I go to test just that: It's good up to 100,000 KHz sine wave 4v peak to peak. Peeping it's performance on my Tektronix 465B w DM44 w/ attached CMC251 Tektronix frequency counter. (Can't ya tell from the flexing - I've joined this dick size contest HEY! YOU GOT THE POUCH FOR PROBES N SUCH! - even though ya got a DM44! No FAIR!) Hangin' out in the breeze, waveform generator's output was 50ohm BNC cable with factory micro test clips. So yeah, about 7" bare separate wires acting as antenners. I musta been pissin' off some local Shortwave radio listeners. I think maybe the Siglent is trash. REAL garbage. Maybe. Aint ever given it a proper real test yet but I have seen it's signals get messy quick under many tests, as close to optimal circumstances as I could get.
I am still a little bit 'bitter' that some Sony person or industry head sent through my then new 2000 Sony ES amp/reciever via Optical input a 'bios' kill switch as to shut down output with a message 'Protector (FAN). In any event, thankfully my old Sherwood I still had since HS was more than an adequate and could keep A. Further noise calls to police at a minimum and B. Did not require additional surround speakers with little compromise (while being forced to only use RCA inputs from TV) given this Sony unit and my 1972 Sherwood already had the Dolby Pro Logic 'circuitry' built in to sound. I also confirmed my 1998 Sony MD recorder would even take a SPDIF/digital signal/covert to analog as to add similar sound coloring like this unit is shown to do (pre-data stage) and dump to disc using same CD EFM 8-14 process Super-Sansui/Shereood/ Sony CD quality copies (also applied to my LP to digital conversions) which this vid has inspired me to provide an upcoming topic. Chris if you get a chance there is a Dolby-to-vendor Vid which 'did its best' to hide the process as all of the 'true' Dolby NR 'global destructive sound' or Noise Reduction only covered tape transfer. I believe there was 27😊 different NR settings they described in video which by virtue of buying singular analog 'chrome' blank tapes at Best Buy that were coming more expensive than a lot of tapes you can buy from your favorite band Sony did a great job of 'passing the torch' and properly applying the Sansui/Sherwood Labs 70's 'space age' analog sound processing was essentially copied and is still the standard for today's THX/DX sound and 'still' sounds good or even better than modern day processors, especially with a standard Stereo LP/CD speaker setup. In the 1990 Dolby Video they did touch on the 'new' '0.1' discrete bass/sub line as to try to impress us 'bass heads' where their then claim is 'bass is funneled 100hz and lower 'bridged' from LF LR C RF RR channels as 'consumers cant tell the difference.'.ha. Now I have seen the latest Dolby Standard is cabable of 6 discrete bass (now subwoofer) location signal locations!. And as a Sansui/Vintage receiever enthusiast the first item you check is to see if the output reciever/amp can handle all of the sub signals in 'bridged mode at 1 ohm stability'😅 jk. Regarding the wonderful videos one of them tested the Technics 2-ch amp with distortion at 1000 hz , but to keep bass heads happy next time us run the scope using a 'minimoog square wave' at either 50-150 hz for the 'true' performance test😊. Maybe consider a new Sansui vs Technics 'Amp-off' using 50-150 hz signal???
'Can beat...' haha thanks to Sony's uni-rust board layout ensured there would not be a way to cut a square in this unit and plug in a Phono 'card' from a Sansui , reinsert the card on the master signal out side so that a test could be made. 😅. Clear synergy from Pioneer and Dolby folks as Sony could not advertise at time same/similar multiplexing to the sound. Also suggest that with these fixes an added cool retro hour-meter so the next round of cap/trans replacements can be timed. Based on past furnace run cap life you got about 5 years and to keep this unit on its toes just leave it plugged in😊. Glad you are enjoying re-transin' and re-cappin' as I would be saying 'ok who was the moron who plugged in the CD jacks into phono, and to be fair the user may have been running the phono to his old receiver and had an amp and was tired of being picked on for having 'old crap' and wanted to show he or she was 'hip to the current sound scene'. If Sony was really 'trying' they could have marketed this unit instead of pushing CD/digital stereo replacements as those switches appeared to mimic old Sansui 'bios relay' boxes which almost guaranteed irate customers as this unit is holding wonky cams responsible for precise low voltage sound output. Also the 'Loudness' labeled as the 0-20 db secondary attenuator was the 'cops are being called' (in my case I found out later my Sherwood S7300 model the Loudness/Lo Filter button only applied to FM selector). No big deal to a bass head like me and Sony also agreed as a few years later they would figure it out and combined with the 20hz cut you could later have the 'Mega Bass' effect (or proper warmth) without having in this case watching my Matushita Technics SL-1200 fall off my rack due to the Sherwood output rumble😊. The 'Loudness' feature also only affected low end response which once the output volume raises to a certain point no longer functions, however if you had good speakers the output is around 100db and you are already head shaking and raising the devil horns. Sony was also a little sneaky by not adding a Phono 'Ground' (or additional hidden signal carrier for some Record players that connected to Sansui/Sherwood receivers) which if used for this 'DSP', sent some customers back to the Sony shop 'looking for blood'. Due to the big hole in getting past album releases to CD, enthusiasts like me would need to wait about 30 years before we can hear Ambrosia's 'One Eighty' in digital form and only being able to hear Billy Joel's 52nd Street or Boz's Silk Degrees on CD left us in the 'digital' dark as Sony/Philips owned the CD patent. Great Video.
Can you suggest guidelines on the TC-399 Reel-To-Reel Tape Recorder. It was working okay (fair) but then it just stop engaging. No forward or reverse movement.
i think the worst brands in the 70´s were Sanyo, Sony and nakamichi(they work perfect when new) , instead of the average of 50 years in all known brands for the 70´s material ,this 3 brands were good for maybe at the most 9 years , nothing else was so bad . The first deck my father bought in mid 70´s from nakamichi ,a 3 head deck it was restored in 86(if memory doesn´t fail me) and it´s working today other components, even bought in early 90´s stoped working in a period from 3 to 6 years, i went dragon and turned into a fly ,the turntable and the deck ,such a good looking pieces but if they only work perfect for a period from 3 to 5 years i don´t know why evenm they talk about the nakamichi brand that much ,the deck is not close to other high-end decks from known brands and the turntable with all it´s modern functions isn´t close to a 45 year old turntable at the time now with 51 years old still works the dragon turntable was a flop good for nothing as the deck, the stasis power amplifier and it´s pre were very nice but sold them before something happened at a non working level
I don't think the issue is where the part is made, if it's a legit source as a lot of the components are made in China. But it's knowing whether the product is genuine. You don't always know what you are getting. I bought a replacement tablet screen from China. Turned out to be a counterfeit and un-useable.
Fabulious video. I have been in this sometimes crazy hobby for over 50 years. Got to bless/curse an uncle who was a ham. I was a real young child walked into his shack one time starting twiddling with the knobs. He came in and instead of anger he sat down and started to explain. Bless you Clint, I still have his old hallacrafters. I have one of these pre-amps tremendous product. To all young guys out there here is something I have experienced. If you come across any pre-amp with no tone controls at a grrage sale etc. BUY it. It's high end. I bought one for 50 turned out to be a 2K dollar pre-amp!!
Hello from Ottawa, Canada. This is a beautiful looking pre - timeless design. I've seen (in their entirety) a few of your videos, including the videos within videos. I really appreciate your videos. Thank you. Recently subbed. Edit: Re: the phono switches. Were the traces destroyed? I'm not even an amateur, and maybe I don't understand / see, but; would not cleaning it up with some flux and gentle scraping reveal the traces? And then, could you rebuild the traces? Thanks
@@vintageaudioaddict You're welcome. I've edited the comment with a question. Was wondering if you could (or anyone else, since I probably missed my chance) could answer? Thanks in advance.
I started to follow you looking for repair audio by my own since I live in Japan and start collect and play vinyls 10 years go, I getting a lot information from you thanks
This is one of the most complete videos on vintage audio servicing and repair videos I have see. I have most of the tools but have been reluctant to use them because all 3 of my vintage recievers sound great as is and I don't want to screw anything up. Furthermore I have tried to build up a list on mouser but I always end up with a list that is thousands items long and I have no idea which to choose. I have this one bookmaker but this morning I started on a board I bough for parts 2 years ago, desoldering components, the first couple went kind of so so, but but the 3rd or 4th I was de-soldering like it was a rivet gun. I now look at replacing the capacitors on my Yamaha CA-610, just the power section at first, if that goes well move on to the amp. and tone controls. If that goes well, I have a CR-620 and a Pioneer SX-780 and a Sansei 551. Great job with the video, I have seen hundreds of these but this was the most complete. Hopefully I can be a "hobbyist" as well someday.
Just want to point out when replacing electrolytic capacitors, that too many people singularly fixate on 105C as better vs 85C. In most cased where 85C is never even approached, it does not matter. What does matter that seemly everyone ignores is design life. Such as an old 85C 10,000-hour or even 18,000-hour capacitor they replace with a 105C rated capacitor with only a 2,000-hour rating thinking it is better. Many 105C 2,000 (or even 1,000) hour rated capacitor are often cheaper than a better quality 85C cap. Those low hour caps are meant for cheap disposable devices, not restorations that are expected to last for decades to come. Those vintage re-cap kits often sold on eBay boast of being a trusted manufacture 105C rated caps, but are actually the cheapest (low hour) series they can find, turning a restoration into waste of time and a future piece of crap.
Hey, no offense man. I appreciate what you're doing here with these videos and all, but you're treating us like we're 3-year-olds you explained for 20 minutes how we needed to clean the cans because the grease was hardened a 6-year-old would have got what you meant a long time ago. It just seems like you wasted a whole lot of time on showing where you needed to clean on the cams and you just kept saying the same thing over and over and over again. I got to clean up this grease right here. It's it's gone hard. I heard that like 10 times in a row. Now I know this is going to probably make you angry and for that I'm sorry because I really do love what you do here. I think you're helping a lot of people, but I'm trying to help you to make better videos. I hope that makes sense to you and I hope you don't thank me too much of an asshole because I do not mean to be.
That was really enjoyable. Good preamplifiers are harder and harder to come by. Good on you for saving one. I did a Yamaha C-80 not long ago that I am very fond of. And before that a Dynaco Pat 4 that I am less fond of.
I want to ask you abouth using vintage equipment designed to work on 220V AC main power. As we know today main power is 230V~250V. In my house is 245V. Please explain is it safe to use that vintage equipment??
I really have no idea. Here in the the USA the normal mains voltage is 120V. In a home about the only appliance that runs on 220V may be a clothes dryer or a central A/C unit.
I worked as an musician audio tech for a dealer that sold Sony. Mark Cohen would have engineers from Sony over from Japan to analyze his audio research preamp and amplifiers he bought from us to see why it sounded so great. Mark Levinson, Harman Kardon, Crown, Krell and many more had better fidelity because the engineers had better ears for design. I was involved with the absolute best in audio reproduction and Sony wasn't it. I dealt with Audio Engineering Society and musicians always seeking to very best. I am talking in the seventies and eighties. Sansui, Pioneer mid fi ho hum .
I would call those (cam followers) That is what we refer to them as in an automotive theater... It's good to come up with a name for things like that that everyone agrees with that way. When you are referring to that part, people know what you're talking about.... That is what makes nomenclature so important.
excellent. I remember that there was quite a bit of Sony around in the 70s, however, the other brands seemed a little more exotic, and those brands came on strong after about '74.
Thanks for the walkthrough on sourcing transistors - just beginning a restoration on a 6500-MKII and boy, there are a lot of parts to renew on this :) The batwing transistors are going to require some ingenuity and research.
This was a great video, I happily watched the whole thing gathering tips throughout!Thank you very much for taking the time to make this, it was extremely insightful! Looking forward to the next video!
Excellent video Chris you gave excellent info for folks just starting out in restoration. As a retired broadcast engineer and do restoration yes those old capacitors have to go keep up the great work, by the way you have some beautiful equipment.
Tons of valuable information. We often replace lubricants when working on vintage gear. We all have a collection of different lubricants for different purposes: plastic grease, lithium grease, moly grease, PTFE lubricants, silicones... I think everyone would benefit from a discussion about different lubricants in different circumstances, and the risks associated with using the wrong lubricants on irreplaceable plastic parts.
Thanks for sharing some great information. I'm always learning as I'm a hobbyist and I'm about as far away from being a chemist as a human being could be. What lubricant is going to damage what plastic in one year or twenty years would be great to know.
I have been saying for a while old sony gear is underrated. My Str V5 receiver is my favorite of all the vintage receivers i own. I have a kenwood, 2 Sansui’s including an 8080db, and a marantz. All are capable and have different wonderful sound. But the sony is definitely my fav. It sounds better to my ears.
@@vintageaudioaddict they sure did. I remember my first 5.1 dolby digital receiver. Still have it. STR DB840. It has an amazing soundstage for an upper mid level surround receiver from the late 90s. Has so many surround fields which actually work for music
Thanks for your videos, I have learned a lot. I need your opinion on a Luxman mq70 that I can purchase near me. The person seems to be a tech. He has pictures doing tech work on it. It is listed on eBay Thanks
Your welcome and thank you for watching. Luxman made some wonderful audio gear back in the day. I have a few pieces but I've never seen a Mq70. I've heard it's an outstanding amp.
Great videos and very detailed, Chris. Can I suggest you take a look at the Technics 9010, 9020, 9030, 9060, and 9070 combo? It is not very known but probably equivalent if not way above this Sony and an improvement even over the Technics 9600. I'd love to hear your take on it and maybe see a video or two about its refurbishment.
@@vintageaudioaddict I have a collection of Sony TVs from about 1970 to the late 80's and most of them are great. They don't have the detail of a new flat screen but the color looks better.
Chris needs to train an army of techs, when the experts of his era are gone the vintage game will be just too big of a gamble outside of basic repairs. Try finding R2R techs, if you find one it's wait forever and repairs cost way more than the deck did.
A question Steve. Quite a few acoustic guitars in close proximity to the speakers in these systems...what if any impact are they likely to have on the sound in the room?
Thanks for the excellent video. I have the Sony TA-E86b pre-amp and the TA-N86B power amp and from the research I have done it seems that the TA-88 series seem to have more problems. The 88 models were top of the range at the time. The TA-E86B uses slider switches and not the rotary type as used in the 88 and I have had no problems with the 86B. I believe that the 88B power amp had problems with their V-Fet power transistors which are hard to find these days. I have had many problems with the 86B power amp's power supply and managed to repair it on two occasions.
Hi Chris, love the tutorial!!! I have to ask as I want to replace the LED panel unit on a Yamaha PC2602M including the LED's...do you have a website I could visit to find a refurbished or new part to go ahead with my project
Hey Sean, thanks for the kind words. For something like what your looking for I'd say eBay would be your best bet. You probably would need to find a donor unit.
Another Great Video...You Do Not Often See Them 2nd hand But I Have The Sony Ta-f248E Amplifier. .Which i bought from new and All Honesty it still delivers a great sound especially through its disc setting...Highly recommended Amplifier
Great Job thanks for the video Sony is a Powerhouse !! Theirs high end companies that would love to have some of Sonys amazing engeeners , Love ro have a sony FA-TA7 integrated amp
@@vintageaudioaddict Yes Sony does their a powerhouse with serous fundage Check out their 8k Heaphone amp Ohhh My Goodness ! Like to see you restore a high end Marantz/Philips or Sony Cd palyer CDM vs KSS 😆 The M/P dac chip 1541 double 👑 is still highly regarded to this day . Thanks again videos looking great Man i know its work , well off to my ABB Robtics class 😥
Jedan majstor mi je za Sony rekao da je ta firma u audio ponudi imala jedan polozen dek,jedan snagas,dva tjunera i 765 magnetofon,.sve ostalo im je sasvim prosecno e cesto i losije od ostalih.
This is great! I need to clean my switches in my TA-E88 and this as given my the confidence to try it out. You should consider changing out the tantalum capacitors in this unit.
It’s a shame what has happened to Sony. But tastes change, as do markets. But if it was not for their PlayStation, and their smart decisions in the motion picture entertainment space, they likely would not be around. But as a shortwave listener, Sony portable world band radios like the ICF-2010 were engineering marvels. I still listen to one- they are truly spectacular.
Thanks for commenting. Yes, it's a different world in many ways from when this preamp was produced. Sony made some amazing electronics back in the day. Look at what wonderful audio products Nakamichi made. Now they are still around mostly in name only. It would be hard to believe Amazon put Sear's out of business if you didn't see it happen. As you said so well "But tastes change, as do markets".
Thank you for watching. Sorry about the omission. Just do a search up here on RUclips there are some really good videos on repairing traces by folks better at it then me. Thanks again.
I can't believe how much quality information is being put out by hobbyists like yourself. I just want to make sure that you know that it's greatly appreciated.
He's beyond hobbyist
That whole pre-esprit series was phenomenal. I was a tech at a Sony authorized service center when they came out and remember going to the weekend training seminar in Chicago. I still have all the "New circuit design" manuals. It was all miles ahead of everything else in every detail. Pure artwork in engineering. It's as if they sat the engineers down and said, "If money were no object...."
I've been doing this as a hobby now for around 5 years. I am an electrician so not a newbie to electricity and circuits but diving into vintage pieces has become completely addictive. I really like your approaches and thought processes. Pretty much binged all your vids once I found you so kudos for all your work and thanks for sharing your talents

Thank you very much!
Got a Sony str 6055 receiver and beats my Marantz for sound in my opinion.
Another great Sony preamp was the later TA-E80ES from 1990. Those switches are gone 👍and back are tone controls, with selectable turnover, in a completely passive tone circuit that can be bypassed through source direct. Useful subsonic filter, balanced in and out, three tape loops and a separate processor loop. Best included MC phono stage I’ve heard, better than my Luxman L-590, but the use of a moving coil step up transformer is always better - quieter. It looks to be much easier to work on than the ‘88 if ever it becomes necessary. Mine still works perfectly after 32 years. Good luck, good health and thanks for all you do!
Thank you so much for sharing and for your kind words. Sony produced a lot of top notch gear back in the day.
This is so gorgeous and way ahead of its time in its looks and design aesthetics if it's a 70s model 😍
Thanks so much for commenting and watching.
Greetings from North London, thanks for all the hard work.I really appreciate your channel. I do think at times people don't appreciate how much time and effort goes into making a RUclips channel like yours. Thank you.
Thank you so much for your kind words. I certainly have much more appreciation for movies, television shows, commercials and as you mentioned RUclips video's. I spend a lot of time on the video's but it keeps me and my mind busy. The video editing has become as much of a hobby as the vintage audio equipment. Thank you again for noticing. Cheers from the USA.
@@vintageaudioaddict I work with people with special needs, I'm also interested in hifi, music and film. I find that channels like yours and others that I follow it's my way of relaxing and when I tell people at work this, I get some funny looks, but I'm the first person they come to if they need any advice.
That Volume Switch look's like the precursor of the Mazda Wankel Engine. This reminds me of a quote: "In many ways, knowledge is easy to acquire; but imagination takes bravery and persistence". Keep these Restorations going!!!!
Will do! Thanks for watching!
This is excellent Chris. Wow. The detail you provide here is great. And the production of your video is also first class. Wow.
I know I’ve left this comment on your videos before, but I wish you were my neighbor, so you can help me repair my vintage audio equipment!!!
Thanks again for these videos, Chris. Cheers!

Jon, thanks a lot. I truly appreciate your kind words.
Would love to use that site, but they are closed to registrations so no access to any of the manuals. Which is a bummer
Man I can’t express how much I am enjoying your videos!! The attention to details and desire to teach others is simply awesome.. Been subscriber for a while but had not looked at more than a couple videos, but after getting into some vintage Marantz and Pioneer units and not having any local repair shops in my area, I remembered your channel..
Today I spent 6 hours watching or better states listening while driving down from College Station after buying some vintage JBLs. Now I am on the hunt for the equipment you referenced so I can start tinkering around!!’
Will be watching and learning !!
Keep up the great work!!
Thank you so much for your kind words. I'm glad that the video's are helping you out. Thanks for watching!

Having a thought here. It’s probably wrong, but who knows.
Is it possible to run a signal through a potentiometer and into an oscilloscope before de-oxidizing and note the wave form? The deox it and test it again to see if it’s fixed? It would save the pain of reassembling and finding out you didn't fix it. Just a thought.
Well.....Probably not. The controls can be so flakey. It would be hard to see on a scope unless the control was really bad. 95% of the time if you clean the control properly you'll be good to go.
1:22 no, just no. Don't do that shaky cam stuff
I've seen a number of "professional technicians" whose work pales in comparison to yours.
Thank you very much for your kind words.
i have no reasons to complain but i bought a sony integrated amplifier in the 70´s and it worked ok but in a matter of maybe 8 years i started to have problems while pioneer and technics components are all working today ,the Pioneers work without ever opening them since 1976 and a receiver from the ES-2000 system that had better finishings than the componets of that year catalog ,it was a receiver ,a turntable and a pair of speakers looking very good at the time, i still use it in my tv room having the matrix 4 option with two extra pair of celestion ditton and not even changed the wires or cables of each component in this system, all working from original maybe i´ll change the speaker cables this summer but i bought it in Japan so i wanted to keep it all original because it´s all written in japanese ,even the instruction inside a plastic cover atatched to the card box are in japanese and written in the perpendicular it´s a long sheet of paper, some years ago i paid 7€ for the brochure with photos and written in english for the first time i ever saw it, this from Ireland on Ebay
Thank you for sharing your experiences that you have had over the years with audio equipment.
Great approach in these latest videos Chris. I loved the Pioneer promo video as I have started collecting vintage stuff myself since my cousin passed a Blue series stack system to me to take over the payments in 1980 as he couldn't afford the hp payments. Apart from the speakers (rotted away) & some slippy belts on the cassette deck it works perfectly well (although I know I should replace the caps). Started collecting after Pioneer taken over by Sounds United... I have cleaned & checked the pots switches & removed any dirt/flux but haven't built up the nerve to strip the SA508 amp caps out yet... Always check new gear as you suggest & remove old dirrt congealed coffee (in 656 mk2) flux etc & spray with WD40 contact cleaner - they've run cooler in every case so far...
Used to make effects pedals for elec guitar in the 70"s when transistors had their own socket mounts they were so expensive!
Many thanks for the videos - so informative & inspiring & getting me restarted! soldering again! Cheers from Portugal
Hi Andy, Greetings from the USA. Thank you so much for sharing your experiences. I'm glad that you have found the video's helpful. With you having past electronics experience I'm sure that any project you take on will be a success.
I have a Sony TA-E1000ESD and it is a marvel of engineering that still works its magic from 1985 to this day. Thanks for your work. Take care.
"I am a hobbyist, I am not an expert on this stuff" 😆😆😆 You definitely made me laugh saying this. Thank you for all your efforts to educate people.
I have a question: Are the Rubicon capacitors a good choice for recap the Sony TA-E88? They have replaced them with 63v 1000mf and they are black :). Thanks for your time!
I love your videos. You have truly inspired me to delve into this hobby as I too share your love of vintage audio equipment and remember going to hi fi stores just to see all of the great equipment that was available back then. I have a question about choosing caps. I know you said it may be good to go up in voltage when choosing a replacement. is there a limit on how much you should increase the rated voltage? Also, can you increase the capacitance or should that remain to what the original cap is?
Thank You for all you do.
Kent, thank you so much for the kind words and for watching. As far as the capacitance goes you should almost always stay with the same value as the original capacitor. The engineers who designed the equipment probably know best. With voltage there really are no issues with maximum voltage rating of capacitors being greater then the originals in vintage audio equipment.
Nippon Chemi-Con, Nichicon, Panasonic are great caps.
Yes, they are.
I just can’t get enough of your videos, the content and detail of the restorations are priceless and I am learning a lot from you. Thank you for sharing your knowledge and your willingness to show the details and workflows. This content is just amazing and priceless
Thank you very much! I'm glad that the videos are helping.
I see on the background a kenwood model 11 like my dad still has.. needs some fixing but its working. do you think its a good receiver?
It's a great receiver! Well worth fixing her up. Thanks for watching.
@@vintageaudioaddict a previous 'technician' destroyed the tuner mechanism.. its still broken. then had a no sound problem, it was the rear pre out switch.
First time on your channel and the cap speech you gave felt like a voice in my head. It's what I've been trying to explain to people since I service electronics, not just audio gear. I've never had any issues using chinese capacitors on any audio equipment and so far no customer has ever complained..Since I'm a little an audiophile myself I've never noticed any difference . I think it's a placebo... No matter the brand I will always trust a new cap more then the old, dried one, no matter where they make them as long as they're reliable...
Thanks for sharing and for watching.
@@vintageaudioaddict I'm currently working on a Technics SU-Z22 integrated amp from 1981 that was so neglected that I almost gave up but now I'm glad I didn't... Very rich sound from STK 2038...
I own a siglent SDG 1032X Arbitrary waveform generator. It's suppoda be good for up to 35MHz. So I go to test just that: It's good up to 100,000 KHz sine wave 4v peak to peak. Peeping it's performance on my Tektronix 465B w DM44 w/ attached CMC251 Tektronix frequency counter. (Can't ya tell from the flexing - I've joined this dick size contest HEY! YOU GOT THE POUCH FOR PROBES N SUCH! - even though ya got a DM44! No FAIR!) Hangin' out in the breeze, waveform generator's output was 50ohm BNC cable with factory micro test clips. So yeah, about 7" bare separate wires acting as antenners. I musta been pissin' off some local Shortwave radio listeners. I think maybe the Siglent is trash. REAL garbage. Maybe. Aint ever given it a proper real test yet but I have seen it's signals get messy quick under many tests, as close to optimal circumstances as I could get.
I had the TA-E86 preamp. Really superb piece och gear, sadly i was stupid enough to sell it like 15 years ago..
love those clips from the factorys!
Thanks so much for watching. The E86 is a nice preamp, the brother to this E88B.
I am still a little bit 'bitter' that some Sony person or industry head sent through my then new 2000 Sony ES amp/reciever via Optical input a 'bios' kill switch as to shut down output with a message 'Protector (FAN). In any event, thankfully my old Sherwood I still had since HS was more than an adequate and could keep A. Further noise calls to police at a minimum and B. Did not require additional surround speakers with little compromise (while being forced to only use RCA inputs from TV) given this Sony unit and my 1972 Sherwood already had the Dolby Pro Logic 'circuitry' built in to sound. I also confirmed my 1998 Sony MD recorder would even take a SPDIF/digital signal/covert to analog as to add similar sound coloring like this unit is shown to do (pre-data stage) and dump to disc using same CD EFM 8-14 process Super-Sansui/Shereood/ Sony CD quality copies (also applied to my LP to digital conversions) which this vid has inspired me to provide an upcoming topic.
Chris if you get a chance there is a Dolby-to-vendor Vid which 'did its best' to hide the process as all of the 'true' Dolby NR 'global destructive sound' or Noise Reduction only covered tape transfer. I believe there was 27😊 different NR settings they described in video which by virtue of buying singular analog 'chrome' blank tapes at Best Buy that were coming more expensive than a lot of tapes you can buy from your favorite band Sony did a great job of 'passing the torch' and properly applying the Sansui/Sherwood Labs 70's 'space age' analog sound processing was essentially copied and is still the standard for today's THX/DX sound and 'still' sounds good or even better than modern day processors, especially with a standard Stereo LP/CD speaker setup.
In the 1990 Dolby Video they did touch on the 'new' '0.1' discrete bass/sub line as to try to impress us 'bass heads' where their then claim is 'bass is funneled 100hz and lower 'bridged' from LF LR C RF RR channels as 'consumers cant tell the difference.'.ha. Now I have seen the latest Dolby Standard is cabable of 6 discrete bass (now subwoofer) location signal locations!. And as a Sansui/Vintage receiever enthusiast the first item you check is to see if the output reciever/amp can handle all of the sub signals in 'bridged mode at 1 ohm stability'😅 jk. Regarding the wonderful videos one of them tested the Technics 2-ch amp with distortion at 1000 hz , but to keep bass heads happy next time us run the scope using a 'minimoog square wave' at either 50-150 hz for the 'true' performance test😊. Maybe consider a new Sansui vs Technics 'Amp-off' using 50-150 hz signal???
'Can beat...' haha thanks to Sony's uni-rust board layout ensured there would not be a way to cut a square in this unit and plug in a Phono 'card' from a Sansui , reinsert the card on the master signal out side so that a test could be made. 😅. Clear synergy from Pioneer and Dolby folks as Sony could not advertise at time same/similar multiplexing to the sound. Also suggest that with these fixes an added cool retro hour-meter so the next round of cap/trans replacements can be timed. Based on past furnace run cap life you got about 5 years and to keep this unit on its toes just leave it plugged in😊. Glad you are enjoying re-transin' and re-cappin' as I would be saying 'ok who was the moron who plugged in the CD jacks into phono, and to be fair the user may have been running the phono to his old receiver and had an amp and was tired of being picked on for having 'old crap' and wanted to show he or she was 'hip to the current sound scene'. If Sony was really 'trying' they could have marketed this unit instead of pushing CD/digital stereo replacements as those switches appeared to mimic old Sansui 'bios relay' boxes which almost guaranteed irate customers as this unit is holding wonky cams responsible for precise low voltage sound output. Also the 'Loudness' labeled as the 0-20 db secondary attenuator was the 'cops are being called' (in my case I found out later my Sherwood S7300 model the Loudness/Lo Filter button only applied to FM selector). No big deal to a bass head like me and Sony also agreed as a few years later they would figure it out and combined with the 20hz cut you could later have the 'Mega Bass' effect (or proper warmth) without having in this case watching my Matushita Technics SL-1200 fall off my rack due to the Sherwood output rumble😊. The 'Loudness' feature also only affected low end response which once the output volume raises to a certain point no longer functions, however if you had good speakers the output is around 100db and you are already head shaking and raising the devil horns. Sony was also a little sneaky by not adding a Phono 'Ground' (or additional hidden signal carrier for some Record players that connected to Sansui/Sherwood receivers) which if used for this 'DSP', sent some customers back to the Sony shop 'looking for blood'. Due to the big hole in getting past album releases to CD, enthusiasts like me would need to wait about 30 years before we can hear Ambrosia's 'One Eighty' in digital form and only being able to hear Billy Joel's 52nd Street or Boz's Silk Degrees on CD left us in the 'digital' dark as Sony/Philips owned the CD patent. Great Video.
Can you suggest guidelines on the TC-399 Reel-To-Reel Tape Recorder. It was working okay (fair) but then it just stop engaging. No forward or reverse movement.
strange chänell..? amd should outperform lower tech ´jäp any year knövv??
Apple products are assembled in Chine designed in USA. The Screens are made by Corning in New York.
Totally wrong on capacitors. We buy direct from Japan still mfg there so your info is wrong.
i think the worst brands in the 70´s were Sanyo, Sony and nakamichi(they work perfect when new) , instead of the average of 50 years in all known brands for the 70´s material ,this 3 brands were good for maybe at the most 9 years , nothing else was so bad . The first deck my father bought in mid 70´s from nakamichi ,a 3 head deck it was restored in 86(if memory doesn´t fail me) and it´s working today other components, even bought in early 90´s stoped working in a period from 3 to 6 years, i went dragon and turned into a fly ,the turntable and the deck ,such a good looking pieces but if they only work perfect for a period from 3 to 5 years i don´t know why evenm they talk about the nakamichi brand that much ,the deck is not close to other high-end decks from known brands and the turntable with all it´s modern functions isn´t close to a 45 year old turntable at the time now with 51 years old still works the dragon turntable was a flop good for nothing as the deck, the stasis power amplifier and it´s pre were very nice but sold them before something happened at a non working level
Do you ever sell any of the units you repair?
No, but I should.
I don't think the issue is where the part is made, if it's a legit source as a lot of the components are made in China. But it's knowing whether the product is genuine. You don't always know what you are getting. I bought a replacement tablet screen from China. Turned out to be a counterfeit and un-useable.
Thank you so much for all your efforts and time helping others in this wonderful hobby.
Chris if you have time. I like to talk about phase liner D500 amp. I want talk about it. You maybe amazed .
Great as you get us used too, long video but really interesting 100%, thanks a lot for your dedication.
So nice of you. Thank you for watching!
Увімкни субтитри.😩Хочу мати переклад
some say only Yamaha C-1 is better then this Sony, or Accuphase c-280, don't know never had any of them
The new capacitors will not out do the old capacitors simple wrong again mate.
Wow
Wonder if an ultrasonic cleaning machice could have cleaned those gummed up switches?
Fabulious video. I have been in this sometimes crazy hobby for over 50 years. Got to bless/curse an uncle who was a ham. I was a real young child walked into his shack one time starting twiddling with the knobs. He came in and instead of anger he sat down and started to explain. Bless you Clint, I still have his old hallacrafters. I have one of these pre-amps tremendous product. To all young guys out there here is something I have experienced. If you come across any pre-amp with no tone controls at a grrage sale etc. BUY it. It's high end. I bought one for 50 turned out to be a 2K dollar pre-amp!!
Thanks so much for the kind words and for sharing.
There's two on Ebay right now. $1350 & $1150.
Old Master lol,respect >.>
Thanks for watching!
Caps can test ok but you need the equipment to test them properly because after 10 or 20 years they leak inturnaly.
Hello from Ottawa, Canada. This is a beautiful looking pre - timeless design. I've seen (in their entirety) a few of your videos, including the videos within videos. I really appreciate your videos. Thank you. Recently subbed.
Edit: Re: the phono switches. Were the traces destroyed? I'm not even an amateur, and maybe I don't understand / see, but; would not cleaning it up with some flux and gentle scraping reveal the traces? And then, could you rebuild the traces? Thanks
Greeting from the USA. Thank you so much for taking the time to comment and for the sub. I do appreciate it.
@@vintageaudioaddict You're welcome. I've edited the comment with a question. Was wondering if you could (or anyone else, since I probably missed my chance) could answer? Thanks in advance.
Sony made some fantastic audio equipment.
One should just be knowledgeable about the models.
Thanks for your effort here.
Your welcome and thank you for watching. Yes, Sony made some top shelf audio equipment back in the day.
I started to follow you looking for repair audio by my own since I live in Japan and start collect and play vinyls 10 years go, I getting a lot information from you thanks
Your welcome. I'm glad that the video's have helped.
This is one of the most complete videos on vintage audio servicing and repair videos I have see. I have most of the tools but have been reluctant to use them because all 3 of my vintage recievers sound great as is and I don't want to screw anything up. Furthermore I have tried to build up a list on mouser but I always end up with a list that is thousands items long and I have no idea which to choose. I have this one bookmaker but this morning I started on a board I bough for parts 2 years ago, desoldering components, the first couple went kind of so so, but but the 3rd or 4th I was de-soldering like it was a rivet gun. I now look at replacing the capacitors on my Yamaha CA-610, just the power section at first, if that goes well move on to the amp. and tone controls. If that goes well, I have a CR-620 and a Pioneer SX-780 and a Sansei 551. Great job with the video, I have seen hundreds of these but this was the most complete. Hopefully I can be a "hobbyist" as well someday.
Thank you so much for watching and for your kind words. Good luck with your projects!
I really appreciate your channel!
Happy to hear that! Thank You!
Just want to point out when replacing electrolytic capacitors, that too many people singularly fixate on 105C as better vs 85C. In most cased where 85C is never even approached, it does not matter. What does matter that seemly everyone ignores is design life. Such as an old 85C 10,000-hour or even 18,000-hour capacitor they replace with a 105C rated capacitor with only a 2,000-hour rating thinking it is better. Many 105C 2,000 (or even 1,000) hour rated capacitor are often cheaper than a better quality 85C cap. Those low hour caps are meant for cheap disposable devices, not restorations that are expected to last for decades to come. Those vintage re-cap kits often sold on eBay boast of being a trusted manufacture 105C rated caps, but are actually the cheapest (low hour) series they can find, turning a restoration into waste of time and a future piece of crap.

Thanks for sharing how to find and select components.
Hey, no offense man. I appreciate what you're doing here with these videos and all, but you're treating us like we're 3-year-olds you explained for 20 minutes how we needed to clean the cans because the grease was hardened a 6-year-old would have got what you meant a long time ago. It just seems like you wasted a whole lot of time on showing where you needed to clean on the cams and you just kept saying the same thing over and over and over again. I got to clean up this grease right here. It's it's gone hard. I heard that like 10 times in a row.
Now I know this is going to probably make you angry and for that I'm sorry because I really do love what you do here. I think you're helping a lot of people, but I'm trying to help you to make better videos. I hope that makes sense to you and I hope you don't thank me too much of an asshole because I do not mean to be.
That was really enjoyable. Good preamplifiers are harder and harder to come by. Good on you for saving one. I did a Yamaha C-80 not long ago that I am very fond of. And before that a Dynaco Pat 4 that I am less fond of.
Thanks for sharing and watching. The old audio gear just needs a little attention and it will be good to go.
I want to ask you abouth using vintage equipment designed to work on 220V AC main power. As we know today main power is 230V~250V. In my house is 245V. Please explain is it safe to use that vintage equipment??
I really have no idea. Here in the the USA the normal mains voltage is 120V. In a home about the only appliance that runs on 220V may be a clothes dryer or a central A/C unit.
I worked as an musician audio tech for a dealer that sold Sony. Mark Cohen would have engineers from Sony over from Japan to analyze his audio research preamp and amplifiers he bought from us to see why it sounded so great. Mark Levinson, Harman Kardon, Crown, Krell and many more had better fidelity because the engineers had better ears for design. I was involved with the absolute best in audio reproduction and Sony wasn't it. I dealt with Audio Engineering Society and musicians always seeking to very best. I am talking in the seventies and eighties. Sansui, Pioneer mid fi ho hum .
Sony, so what
this must look ouer kids because they dont know this past.
I would call those (cam followers)
That is what we refer to them as in an automotive theater... It's good to come up with a name for things like that that everyone agrees with that way. When you are referring to that part, people know what you're talking about.... That is what makes nomenclature so important.
excellent. I remember that there was quite a bit of Sony around in the 70s, however, the other brands seemed a little more exotic, and those brands came on strong after about '74.
Thanks for watching!
Thanks for the walkthrough on sourcing transistors - just beginning a restoration on a 6500-MKII and boy, there are a lot of parts to renew on this :) The batwing transistors are going to require some ingenuity and research.
Your welcome. I'm glad that the video helped and thanks for watching.
This was a great video, I happily watched the whole thing gathering tips throughout!Thank you very much for taking the time to make this, it was extremely insightful! Looking forward to the next video!
Glad it was helpful! Thank you so much for watching!
Excellent video Chris you gave excellent info for folks just starting out in restoration. As a retired broadcast engineer and do restoration yes those old capacitors have to go keep up the great work, by the way you have some beautiful equipment.
Alan, thank you very much for your kind words. I really appreciate it.
Sony, Kenwood and a few others made some really high-end stuff in the late 70's through the 80's.
Yes, they sure did. Thanks for commenting.
What’s the model number again?
Tons of valuable information. We often replace lubricants when working on vintage gear. We all have a collection of different lubricants for different purposes: plastic grease, lithium grease, moly grease, PTFE lubricants, silicones... I think everyone would benefit from a discussion about different lubricants in different circumstances, and the risks associated with using the wrong lubricants on irreplaceable plastic parts.
Thanks for sharing some great information. I'm always learning as I'm a hobbyist and I'm about as far away from being a chemist as a human being could be. What lubricant is going to damage what plastic in one year or twenty years would be great to know.
Do they still make Technics SL series drive lube packets where there is a cutout below the metal spinner?
excellent
Many many thanks
Helpful whete did you get the desolering gun?
I have been saying for a while old sony gear is underrated. My Str V5 receiver is my favorite of all the vintage receivers i own. I have a kenwood, 2 Sansui’s including an 8080db, and a marantz. All are capable and have different wonderful sound. But the sony is definitely my fav. It sounds better to my ears.
Thanks for sharing. Sony made some great gear back in the day.
@@vintageaudioaddict they sure did. I remember my first 5.1 dolby digital receiver. Still have it. STR DB840. It has an amazing soundstage for an upper mid level surround receiver from the late 90s. Has so many surround fields which actually work for music
Thanks for your videos, I have learned a lot. I need your opinion on a Luxman mq70 that I can purchase near me. The person seems to be a tech. He has pictures doing tech work on it. It is listed on eBay Thanks
Your welcome and thank you for watching. Luxman made some wonderful audio gear back in the day. I have a few pieces but I've never seen a Mq70. I've heard it's an outstanding amp.
@@vintageaudioaddict thanks
I think the design is too complicated for a preamp... 🤷♂
me too! lol
I just reached out to a audio tech to have a TEAC cassette tape player repaired. I am excited to have found someone that is even able to do such work.
That is awesome! Your correct, it is difficult to find techs that will work on the older gear.
@@vintageaudioaddict
If you or other people live in Toledo Ohio or Ann Arbor Michigan I have a few places to get high end audio repairs done.
Anything MIJ back then was not considered to be good quality... these days vintage and new MIJ equipment is considered te Apex of quality.
Great videos and very detailed, Chris. Can I suggest you take a look at the Technics 9010, 9020, 9030, 9060, and 9070 combo? It is not very known but probably equivalent if not way above this Sony and an improvement even over the Technics 9600. I'd love to hear your take on it and maybe see a video or two about its refurbishment.
Sony made a name with the Trinitron TV and that's what they became known for, great TV's. Even TV stations used them to monitor their broadcasts.
I owned a Trinitron in the 1980's. They were great TV's.
@@vintageaudioaddict I have a collection of Sony TVs from about 1970 to the late 80's and most of them are great. They don't have the detail of a new flat screen but the color looks better.
Chris needs to train an army of techs, when the experts of his era are gone the vintage game will be just too big of a gamble outside of basic repairs. Try finding R2R techs, if you find one it's wait forever and repairs cost way more than the deck did.
A question Steve. Quite a few acoustic guitars in close proximity to the speakers in these systems...what if any impact are they likely to have on the sound in the room?
Do you think that the Pioneer A-757/777 sounds like crap, many complain that even though it is nicely built the sound is not as expected.
I've never listened to that model but everyone has a different set of ears. It's what sounds good to you that matters.
I love you
Thanks for watching!

If device npn how test pnp
I like the hammer that the production line worker used on on the tube tv. It is the way to fix a television.
There are all of these grannies living in Japan with expert electronics skills, seems strange to think about it.
Thanks for the excellent video. I have the Sony TA-E86b pre-amp and the TA-N86B power amp and from the research I have done it seems that the TA-88 series seem to have more problems. The 88 models were top of the range at the time. The TA-E86B uses slider switches and not the rotary type as used in the 88 and I have had no problems with the 86B. I believe that the 88B power amp had problems with their V-Fet power transistors which are hard to find these days. I have had many problems with the 86B power amp's power supply and managed to repair it on two occasions.
Thank you for the kind words and for sharing your experiences. Sony made some great audio gear back in the day.
It is too long .. better to have 2 or 3 times 1 hour

Hi Chris, love the tutorial!!! I have to ask as I want to replace the LED panel unit on a Yamaha PC2602M including the LED's...do you have a website I could visit to find a refurbished or new part to go ahead with my project
Hey Sean, thanks for the kind words. For something like what your looking for I'd say eBay would be your best bet. You probably would need to find a donor unit.

Hvala na gledanju
This is great! I need to clean my switches in my TA-E88 and this as given my the confidence to try it out. You should consider changing out the tantalum capacitors in this unit.
I'm glad it helped! I did change out the tantalums. I had shot the video/pictures before I had changed them out.
It’s a shame what has happened to Sony. But tastes change, as do markets. But if it was not for their PlayStation, and their smart decisions in the motion picture entertainment space, they likely would not be around. But as a shortwave listener, Sony portable world band radios like the ICF-2010 were engineering marvels. I still listen to one- they are truly spectacular.
Thanks for commenting. Yes, it's a different world in many ways from when this preamp was produced. Sony made some amazing electronics back in the day. Look at what wonderful audio products Nakamichi made. Now they are still around mostly in name only. It would be hard to believe Amazon put Sear's out of business if you didn't see it happen. As you said so well "But tastes change, as do markets".
