Mark repairs a Technics tape deck, with a rather alarming fault. Literally like an alarm... a loud screaching noise comes from one channel. And what else is up with it?
This channel is a great pick me up. The unrelenting cheerfulness is a decent tonic if you've had a crap day. Watching someone skilled at their job who takes pride their work is a delight, too.
It is really satisfying to watch someone who's so enthusiastic about his work. I know nothing about electronics or stereos, but it's a great to learn. Thank you for sharing!
That PCB looks top notch if you compare it to Philips reel to reel recorders PCBs from the same era. Really a quality difference to notice. Nice deck repaired by a nice chap with exceptional care and love.
Wow, I just stumbled on this video and I am transfixed! That is a beautiful deck and if any of my audio equipment became faulty, I'd want you to repair it. So professional. As an aside, you sound Brummie. I am from that part of the world. Brilliant!
Very patient in identifying and rectifying the defects! I liked very much the fineness in soldering the Capacitors Etc along with unscrewing and screwing of the screws! A thorough knowledge of the Circuit will alone make you perfect in finishing and getting success in your endeavour! With Best Wishes!!
I bet you've never seen a pulley on a cassette recorder so big and heavy. I had also never seen one so big until I took apart my Technics RS-641 which has a mechanism like this one (except the motor which in my case is servo assisted and is at the front). I have kept the original belt and pinch roller and over 40 years of use and abuse both continue to function satisfactorily. I admired the skill and ease with which you unsoldered the rec/play switch to clean it. (Something I was supposed to do on mine and haven't done yet.) As always, good job!
I repaired several Techics equipment, but without using an oscilloscope, I did not have the money to have one. I repaired many switches, which is a very common failure, sometimes cleaning and changing their parts from other switches, which were recycled. I also replaced flat and round belts, heads, roller pin and other spare parts, good video, greetings from Chile.-
Mark, very interesting video, thanks. I watched you remove the record/ play switch, what a lot of time and effort, not to mention the chance of damage to the switch. I had Hi -Fi repair business in Seven Hills NSW Australia for over 40 Years. repairing literally thousands of tape decks. I can say I never found it necessary to remove any of these switches. I what we did, firstly remove the mechanical connection then, spray "CRC Contact Cleaner" with a bent spray tube in one end of the switch, while pushing the switch back and fourth rigorously, making sure the spray came out the other end. Then to finish the clean would give a light spray with "CRC 2.26". I never had even one tape deck for that repeat fault ever, to the best of my knowledge.
Nice job. I think the only thing I would have added to the list would be to adjust the playback level so the Dolby circuit was tracking properly. These days people primarily use these decks for playback, but if they plan to use it to record going through the record alignment would also be in order.
especially after all those cap replacements. There is bound to be some alignment issues despite the improvement in long term reliability. (also was probably out of spec due to 40 years of aging parts.)
Tough way to clean the slide switch. De-ox spray would have been my choice. Before desolder tabs on thru hole, melt some fresh rosin solder on each tab. This flows any of the old solder to mix with new flux. Then the solder sucker iron will easily evacuate the molten metal on the feed thru and trace surfaces. Those slide switch contacts could use burnishing tool strips of fine or extra sensitive grade. When relay contacts were common, those burnishing tools saved replacing the relay. The burnish strips would leave no residue.
This is a rather common prob on these machines. You MIGHT get away with using contact cleaner and wiggle the switch "a gazillion" times or running it through the ultrasonic cleaner, but taking it apart and cleaning it by hand ensures that it'll take a good while before the problem occurs again. I'm using the same method as you do and it works just perfectly. The green goo is oxidation mixed with contact grease and probably a good ammount of tar and acid from smoking. It will create all sorts of funny things in the switch, causing the feedback. I've done this operation many times and the only things I'd do differently would be to NOT use the glass-fibre brush - or at least blow the loose fibres away from the switch innards - and also lubricate the switch with contact grease (acid-free vaseline or silicone grease) before assembly. Now if I remember correctly, there's most probably another little switch in the mechanism as well, controling the mute function when pausing or cueing. When this little switch gets dirty and loses contact, the output will be VERY low during playback. Quick solution; clean the contact surfaces and the prob is gone. :) Anyways, thank you so much for a great video, keep up the good work!:)
You are a genius man.. How is this possible?!! The devices that you repair are very difficult. Also, how can there be spare parts in this time? I am very honored to be following you... especially the devices of the seventies period. Thank you.
I just bought my technics cassette deck from our local flea market but mines is from the 1982 my deck also had the right channel was aslo having audio problems but i took the cover off and sprayed the the same exact part with contact cleaner and it fixed my right channel and i put the cover back on
I honestly would believe , in that era, the lubricant in the switch was factory and it had never been cleaned before. The factory lubricant pretty well stops these switches corroding and going black. Technics use to be quite high end in the day
Love the video love your work, but considering how hard it is to get to the pinch roller and the fact that it looked a little glazed I would have replaced the pinch roller. I just worked on a Hitachi D900 and it was the pinch roller that was causing it to eat tapes. And changing the pinch roller can really smooth out the replay of the tape. But great videos I have liked and subscribed.
Those caps, I expected that... Have done a few Technics decks from that era (including a friends RS-1500 Reel to reel deck) and all of them had these blue Matsushita branded caps with corroded legs. They are always replaced when seen...
I've got one of them in my loft. And a Beta video and a CD player and the smaller parts of an old piano and a Triang train set from 1966 and some wood and some decorating stuff and a tent and two camping stoves and...
Recently I acquired a RS-M15, not sure how they differ from the 17's. Have yet to connect it up to period correct HiFi I've bought separately. So not sure if it works (and how good).
I saw you repair the long SWITCH on your video about the RS-M17. I have a RS-808 Panasonic, and amateur ME sprayed said SWITCH with CRC Lectric component cleaner, and it welded my SWITCH. It is melted in PLAY mode, and I have no ability to find part, OR no ability to DeSolder and reinstall like YOU. Do you take units In for Repairs ? Just asking. Otherwise, where Can I get that SWITCH for my RS808 Technics number, I have no schematic, and it is made by Matsushita. Thanks Greg / Houston
Your game pulling that switch apart, I have had a couple of old 70's sony amps with large slide switch issues, they are very tricky, they had more slides and contacts much smaller and with small springs, total headache.
Great videos,just found them that was a stupid design, ALL tape decks failed because of that baddly thought out slider multi switch,hated them,still do; have a few decks here and there with that same defect; now that i see how easily you do it,i may go back to them; i wick up the solder with peices of wire soaked in flux greeetings from Portugal
good day sir I really like the know-how that you have, can you give me the brand and reference of the desoldering gun that I find very effective with a big thank you in advance.
I picked up technics SA380 , mfg in 1982 for 5$ , it's capacitors are still working.but the tape mechanism is gone due to some idiot trying to repair it . Using it as an amplifier( STK 4141 50W/ch ) only
Attention to detail and going the extra mile to do the right thing for the customer (replacing leaky caps for example) - excellent work. The humor is icing on the cake.
Yes, the play/rec switch is a classic. I guessed as much a few minutes in the video. Usually corosion or grime from too little use/sitting still. My first try would be to just flick the switch a couple of times: usually fixes it, but I love the very thorough approach Mark.
Exactly! Quick spray with DeOxit, slide back and forth... Volia' 10 minute repair which makes way more sense with a $79 deck. I enjoy his videos but this one had me yelling at my laptop.
I love watching how simple you make it look and remembering where all the screws go. And there's a whole new generation out there that don't know what wow and flutter is.
I appreciate the extent you go to clean such a switch. I just spray some DeOxit, or what have you, in it as best I can and then actuate it 50+ times. If there is still noise or signal drop I repeat the process. If I've done it 3 times and it's still having issues I usually give up. lol. But seeing how you attack this problem gives me some pointers to try when I get back around to those machines that are on my "try again later" shelf. In fact have an Akai GX-747 open reel deck that I got for a steal because it has issues with a channel dropping. I managed to get most of the issues resolved using my "spray and pray" method but I'm sitll getting one channel to drop out occasionally.It was the record/play switch that was the offending component in fact. So I'm going to try and take it apart for a proper cleaning. I bet that will solve the issues for good now.Thanks.
I watch with baited breath so I can gleen a small fraction of knowledge from watching you repair these electronic gadgets. But alas, I'm lazy and just let you do all the work and basically absorb nothing. It's much too easy just to let you do everything and me absorb nothing. I cringe every time you take apart one of these multiple switches, because I know if I did it parts would mysteriously loose themselves and somehow my chubby fingers would not be able to get it back together. Love the channel, love the videos.
I'm sure I have a couple of old Technics tape decks stashed away in the garage. I'm now inspired to dig them out and see if they are still operational. 🤔 Great video, as always.
Hi and thank you for sharing an interesting and entertaining video. My father was an TV technician, and I often visited his workshop. In those days, the 1970s, the technicians were wearing white coats. A word of warning and care though. When you cut those end bits of the capacitors, please remove them one by one as you go along. The way you did it, cutting them and turning the unit around to shake them out, one of them could get caught in there and cause a shortcut.
I was assuming that he was doing that for the sake of a better video, not having two hands in there blocking the view. Otherwise, having bits of wire flying around in an electrical device… what could go wrong? ;) … I love his channel though.
You crack me up Mark, great little channel and reminds me of my time as an Electronics Eng and my youth being Mr fix it. Watch those glass fibre strands left in the switch though 🤣 luckily they arent strands of wire! Great show, looking forward to watching some more
Brilliant job and great video. It was interesting to see inside that M17, my first Technics deck was an RS M12. It looked almost the same to be honest I can see the older Technics equipment was quite well put together. I now wish I still had my M12 to have a look inside. Thanks again.
You have done a wonderful job with this tape recorder. Congratulations! That multiple switch (play/record) is the cause of many problems. I would have also changed the capacitors from power supply block (sometimes they produce low frequency noises. Especially when they are old). You have a great channel YT!
Meticulously desoldering and soldering of that centipede switch and caps. Polishing the motor shaft and those copper bits of the forementioned switch shows how thurel you have to be with those 70's decks. Subscribed in a jiffy 👍🏼
I have that same model. Don’t use it much anymore, but last time I did it worked fine. So many little fiddly parts that I would not even crack the panels open. Enjoyed watching you do it Mark!
Another GREAT video. One small note, Demag should be turned on at a distance and kept on until withdrawn to at a distance. The demag will produce a large magnetizing pulse upon switch ON and OFF. Also a Demag may interfere with a nearby pacemaker.
Quite possibly the happiest chap on RUclips. I come for the repair entertainment, I stay for the smile and the bright blue eyes! Good work mate! Consider me a sub! :)
Those record switches are typical for Technics decks. You don't have to remove it and open it, just spay it with some DeoxIT D100 and you're good to go.
I used to repair cassettes-back in the day I would have been straight in with switch cleaner before checking anything with a meter or change the switch if the cleaner didn't work- no taking it apart carefully (which is the better approach these days given switches are harder to come by). I have all but stopped repairing them now and sold off all my better decks v cheaply although many were in a part dismantled condition and scrapped anything with mechanical keys. Still left with about 35 cheaper decks the most similar but later to this that I still have is the RSM216. Things are very different now and I love the care you take to make these oldies probably work for many more years but now we are not under pressure to fix loads in one day every day as was a typical commercial setup.
Wow! Nice restauration of this humble cassette deck. That pinch roller looked a bit crispy though... Good idea to replace this? Helps a bunch with those wow and flutter issues... with the belt replaced it should be a 100% restore to factory spec?
A dirty Record/Play Multiswitch is often the cause of noisey playback. I tend to 'wash' them with Servisol Super 10 or a direct equivalent. I only ever once opened one of these switches up. I like the meters on this deck.
Love this (older) stuff - so nicely serviceable, designed to be serviced, with service manuals, unlike some of today's throwaway junk (both cheap and expensive!).
Hi Mark. Where are you buying your rubber belts ? I need one for my Technics M6 ( similar/same mechanism). Tried the Chinese ones, but they are woeful.. Thks
Actually the gear that get s chiped it s in front of the mechanism,not on the back.Happened the same to me when i tried to fix one but in the end the microprocesor died due to a short from the crap wiring from the back of the mechanism..

Centipede switch, that's a lot of legs😂. Thanks for opening it up and showing us, that was a treat!
What I like about Mark? He’s a Jolly good Fellow, he has a million Pound smile,Keep those vintage sets running. Love to watch your vidros
Vintage casette decks and radios 📻 are an emotion 😢❤❤❤❤
That switch repair was beautiful. You seem to do these things so effortlessly…Bravo
كم احب هذه الاجهزة و التحف انا ايضا وعندي منها تلاثة معطلين ولم اجد فنانا مثلك يصلحهم لي ..تحياتي لك من المغرب
I've always loved the aesthetic of early 80's hi-fi separates. The brush silver aluminium finishes and yellow, red and/or green LEDs.

Mark I just wanted to say your calm voice and demeanor is a pleasure to watch
I have a very similar model (M11) with slow playback and the screeching noise. This video helped to fix both problems
Wow...I really wanna know how much actual time that repair took!!! Love tge humor and the attention to details

A video suggestion: Your thoughts, experience and recommendations about grease and lubricants in these old electronics products.
Excellent work and awesome humor.
Awesome love your work.
I honestly would believe , in that era, the lubricant in the switch was factory and it had never been cleaned before. The factory lubricant pretty well stops these switches corroding and going black. Technics use to be quite high end in the day
in technics cassette decks of this vintage, it's almost *always* the long rec/pb switch that needs exercise & cleaning fluids.
When he cut those extra length of capacitor lugs after soldering, I closed my eyes as an involuntary response
Love the video love your work, but considering how hard it is to get to the pinch roller and the fact that it looked a little glazed I would have replaced the pinch roller.

Great job one more time !
Hoping that "test" tape was a lucky enough shot. There's no calibration to IEC standard without lab grade full track tapes.
good day sir
I really like the know-how that you have, can you give me the brand and reference of the desoldering gun that I find very effective with a big thank you in advance.
Before installation, lubricate the contact groups with petroleum jelly.
Excelente programa ...solo 🙏porfavor pudiera ser subtitulado al español
Impressed
Столько скурпулёзной работы для такой простой деки))
Gobs of grease absorb pollution from the air and make the contacts marinate.

Love these videos Mark. You are the Bob Ross of audio repair.
Yes!!!!
Ad Big Clive is the Bob Ross of teardowns.
Well said 👍
one of my favourite channels, your chipper manner always brightens my day Mark!
Never thought I would love watching audio repairs, but this is pure gold!! You are amazing!!
Those of us who listened to music in the 80s like a bit of Technics 😁
I love Technics. Panasonics premium brand i think
You are a pro. Not a single screw left over. I swear I end up with more screws on my bench than in the device when I'm done with it!
Not really, he recorded everything on video so he could see where everything goes.
Attention to detail and going the extra mile to do the right thing for the customer (replacing leaky caps for example) - excellent work. The humor is icing on the cake.
Any professional tech will replace leaky caps as a matter of course.
Yes, the play/rec switch is a classic. I guessed as much a few minutes in the video. Usually corosion or grime from too little use/sitting still.
My first try would be to just flick the switch a couple of times: usually fixes it, but I love the very thorough approach Mark.
Exactly! Quick spray with DeOxit, slide back and forth... Volia' 10 minute repair which makes way more sense with a $79 deck. I enjoy his videos but this one had me yelling at my laptop.

I love watching how simple you make it look and remembering where all the screws go. And there's a whole new generation out there that don't know what wow and flutter is.
dont be so sure boomer. WOW is world of warcraft, and flutter is flavored Butter. See we arent ALL stupid.
@@billyghostal😂😂😂 ggg drrrr
A lid that goes on the bottom - you'll never know what its called because its under cover ;)

When i watched your video, i just back to in 1990 my childhood time , excellent work you done,🥰🥰❤❤ love you stay blessed, where you from
Love the de-magnetising head practical - thanks for showing us that Mark. Yet another great video and up to your top standard.
35:42 35:49 is that editing problem or any other thing?😅

Hi Mark, I appreciate the knowledge you share through your videos. Further, I love your humility and humour and jovial approach. All the best always!
Has anyone ever checked out Mr Carlson's Lab? That guy is a real genius.
mark u have so smiling face. 😃
Hi Mark, I hope you didn't forget the nail varnish on the azimuth adjustment screw😂 I did once and after a few plays it had to be adjusted again.
I have that same model. Don’t use it much anymore, but last time I did it worked fine. So many little fiddly parts that I would not even crack the panels open. Enjoyed watching you do it Mark!
Another GREAT video. One small note, Demag should be turned on at a distance and kept on until withdrawn to at a distance. The demag will produce a large magnetizing pulse upon switch ON and OFF. Also a Demag may interfere with a nearby pacemaker.
always a pleasure to watch for us old-time soldering iron-n-scope lads!! Attention to detail always pays-off. Keep up the good work, Mark!!👏👏
I don't understand what you're saying, but I understand what you're doing. Thank you.

Things are very different now and I love the care you take to make these oldies probably work for many more years but now we are not under pressure to fix loads in one day every day as was a typical commercial setup.
nice job - but didn't you forget to use contact grease like SGB 2GX when re-fitting the contact sliders ??
I've never seen such a cheerful guy. And great professional :)
Wow! Nice restauration of this humble cassette deck.
That pinch roller looked a bit crispy though... Good idea to replace this? Helps a bunch with those wow and flutter issues... with the belt replaced it should be a 100% restore to factory spec?
A dirty Record/Play Multiswitch is often the cause of noisey playback. I tend to 'wash' them with Servisol Super 10 or a direct equivalent. I only ever once opened one of these switches up.
I like the meters on this deck.
Love this (older) stuff - so nicely serviceable, designed to be serviced, with service manuals, unlike some of today's throwaway junk (both cheap and expensive!).
Exactly.
That was my tape deck during college!
share a video with remplace of belt in Pioneer ctf 1250 please
Hi Mark. Where are you buying your rubber belts ? I need one for my Technics M6 ( similar/same mechanism). Tried the Chinese ones, but they are woeful.. Thks
Actually the gear that get s chiped it s in front of the mechanism,not on the back.Happened the same to me when i tried to fix one but in the end the microprocesor died due to a short from the crap wiring from the back of the mechanism..
