Sansui BA-5000. The Most Famous And Powerful Amplifier Ever! Will Drive Any Speaker To It's Knee's!
HTML-код
- Опубликовано: 1 окт 2024
- One of my favorites! This BA-5000 vintage stereo amplifier is one of the most highly regarded products ever produced by Sansui. This was a top to bottom repair and restoration that after 40+ years of service this vintage amplifier needed. This Sansui CA-5000 was in terrible cosmetic shape when I obtained and it needed the old electrolytic capacitors, troublesome diodes and transistors replaced. This is the only Sansui audio product that ever used output transformers. 300 watts into 2, 4, or 8 ohm speakers.

You have the heart of a true teacher. Isn’t experience a wonderful thing? You’ve got it.
Thanks for watching!
I lusted after Sansui stereos in Jr High school.
glad to see they are not all dead
Ya, me too. Back then my Pizza Hut income limited me.
I found a Sansui BA 3000 amplifier at my local Goodwill about a year ago. Mint Condition. $16. Wonderful amplifier.
Very nice!
Holy crap! What a bargain!
I think I saw one at goodwill too. Not sure if it was a sansui because i wasn't into vintage audio equipment then. But it was a rack mountable one that looked really similar to the one in the video. Kicking myself for not getting it now lol
Wtf??
You're a guy right up my alley. I've been tearing apart and fixing things since I was 4 or 5 years old, I'm 62. Every time I get something that's gone bad and I can't fix it, I tear it apart to see how the engineers designed it and how it was put together. I'll 2nd always taking before and after pictures, your phone is right there, use it. Enjoyed your video and I will watch more. Cheers 🥃
Thanks a lot for sharing and for watching.
Got a 9090 db need a panel fuse holder just screw in part who has one
I had no trouble watching this video in its entirety. I enjoyed it from the start all the to the end. For a non professional you have a pretty good idea of what’s happening or what’s supposed to be happening at the different stages of the amplifiers circuit . Your non-professional way of explaining the electronics - IMHO - is a real strength and what kept me on board for the whole ride for the first time ever watching this type of video. This isn’t the first electronics repair/ restoration video I’ve watched but it is the first one I finished. I thank you for the education and the entertainment!
What a beautiful amp! I love Sansui amps as well. You are a very generous man to give away your trouble-shooting information and share your trouble-shooting techniques. I can’t agree more with everything you said about how using a good channel can be your best friend and many other things. Once a person can identify and have a basic understanding of what the different blocks of the schematic are doing, troubleshooting becomes much easier. I love that most all amps simply mirror the other channel in board layout design. I hate schematics that continue off across many pages of paper. I have even printed in tiles and cut out and taped multiple pages together to get a larger diagram to view, or to help follow the signal onto another schematics page. I once had a Ranger 2950 Transceiver schematic download printed from my thumb drive at a local office store in huge paper format of approx 3’x3’ just so I could see it well. You provide many helpful and practical tips. I have learned same way as you have over the past 35 years. I sure wish I had some of your beautiful pieces of test equipment. However it is amazing how many things can be fixed just with a decent multi-meter, ESR type Cap tester and Cap value tester and a decent solder station. My most recent tool purchased was the Hakko desoldering gun, a bit pricey but wow, how very helpful for removing a single transistor lead for testing or pulling off whole components quickly. Your getting me interested in going back to work again, lol. Best wishes always my friend and thank you for your videos, I love watching them.
Mike, thank you so much for your kind words. It's difficult for owners of vintage audio equipment to find a technician in today's world. I hope that the video's help folks to keep their vintage equipment operating. Thanks again Mike and good luck with all of your projects.
@@vintageaudioaddict I have a Sansui 9090 that was given to me, cant wait to crack into it and figure out its issues. I worked on it many years ago before the owner passed, his best friend then gave it to me. I remember it was a unit that also was plagued by noise in the sealed type switches. After figuring out the main issue, maybe these switches can be opened up and cleaned if no replacements are available, ”if still plagued with this issue?” Would love to hook up my Technics SL1200MK2 to it and use it as my main home unit.
😎👍
Thank you for posting this! A great save on one of the best audio power amplifiers ever made; you don't often see these out in the wild...in any condition. I listened to one of these that belonged to a coworker back in the late 70's-early 80's through a pair of Pioneer HPM-150's; just an amazing sound, regardless of the type of music...those really were the days! This is one of those units you could call the holy grail, Sansui made some of the best equipment during this period. Thanks again for your time; a rare piece of audio equipment lives on! This really was a great save!
Thank you so very much for your kind words. She is a wonderful example of the quality that went into the engineering and manufacturing of audio equipment in the 1970's.
What a great video! Im just getting into this hobby and im learning the same way. But you have just a great way of explaing basic trouble shooting. Thanks!
Thank you for the kind words!
Wonderful job showing a classic piece of Sansui gear. I owned two CA-3000 preamps from the same Definition Series and always dreamed of mating it with either the BA-3000 or the BA-5000. Never could find one. Like you, I collected a ton of audio brochures during my teen years and I was going to offer to give you my Definition Series brochure but it looks like you already have one. Did you ever figure out where those original bias transistors were mounted. Sure looked weird hanging out there in mid-air wrapped in tape! ;-)
Thank you for watching. Yes, the original bias transistors were mounted in clips that were attached to the heatsink/power transistor assembly. The clips were still attached to the assembly. I used the same clips and mounting hardware for my replacements. I'd love to have a CA-3000 to match up with my BA-5000. Maybe someday......
I always await your videos, Chris. Another informative adventure, down Vintage Audio Lane!
Glad you like them!
WOW, what a beast, a keeper for sure
She is a beast alright. It feels like I'm picking up a motorcycle engine when I move it.
Thank you Vintage Audio Addict, the contents you bring us really justify your enthusiasm. Beast of an amp.
Thank you so much for watching!
I remember this amp when i worked in the trade back in 1975-1976 era, thats not an amp its a welding device a power station, i remember seeing one with its preamp and i was blown away by its size and weight
Thanks for sharing. Yes, she is a heavyweight.
@@vintageaudioaddict did you ever see the Luxman M6000 my god that was a beast stunningly beautiful
and a clone of the Mcintosh mc 2300........
@@kwd-kwd I’ve got the McIntosh 2500 and 2600…. Yes, MASSIVE.
HI ¡ ... GREAT VIDEO ... What do u think about Technics SE-A3 MK2 ? , Pioneer Exclusive M5 ? , Onkyo M-510 Grand Integra ? , Accuphase PX-650 ? , Marantz SM1000 ? ... SALUDOS DESDE MEXICO 👌
Thank you and greetings from the USA. Those are all very good pieces. Most of the older audio equipment was built to last and it has.
Your wife made the deal for you? Any lessons here for how to do this?
Man, I'm pretty lucky. As for the secret....well, I don't have one. She has always supported my vintage audio hobby(addiction?). She gets more upset then me when I leave something behind. I'm so glad she went back and got this BA-5000 for me. It's one of my favorites.
This amp is almost as beautiful as your wife.
Im drooling. My god thats beautiful.
Thanks for watching.
@@vintageaudioaddict always!!!
Have you ever listened to some quadraphonic LP's?
I had a table / cabinet that was a quadraphonic turntable / two speakers / album storage all in one that had two satellite speakers. I bought it at a yard sale when I was 14 with money I earned bagging groceries and doing late night floor cleaning buffing waxing on an air force base at their headquarters building. My dad drove me around through six states tracking down specific albums that were quadraphonic. That was in the mid 70's. He thought it was the neatest thing 'since sliced bread. I left it with him when I went in the Army. One day in 2012 I had to fly out to his funeral. My sister called me into his bar room / five car indoor fully finished heated living space garage that he built. There it was. A note on the back he had pasted on said "Rebuilt by (his name) on (date)." He had collected another for parts, had a few styluses, needles, entire cartridges, replacement parts in bags and labelled. He bought a pallet rack for the parts unit and speakers. A list of components replaced, their values. His neighbor came over and said he stayed in that room working on his harley or his Indian just wrenching, drinking cans of Pabst and changing albums. A Jefferson Airplane album was left on it. I turned my back on it. I couldn't take looking at it, for it would remind me of how I miss him every time I wanted to listen to it.
Maybe? A long time ago. Sorry about your dad but thanks so much for sharing his and your story. Vintage audio equipment and music was a big part of many kids/young adults life's growing up in the 60's and 70's like myself.
always wanted that when I first got into audio. it's crazy but I think the vintage gear sounds better imo! The newer amps and receivers don't have the same sound.
Totally agree!
This guy sounds like Tom Bodett,the guy who did those "Motel 6" commercials...
I keep waiting to hear him say,"we'll leave the light on for you."
lol
My older brother had a Sansui 90/90 DB with a pair of Technics SB7000A's back in the mid to late 70's. That system sounded great.
Thanks for sharing!
I totally agree with your comments and I'd wish that I had proper guidance. Looking back at all the broken vintage audio equipment that I could've had repaired. Anyway vintage Sansui is excellent quality. Take care and keep up the great work.
Thank you for watching and for sharing.
Outstanding restoration. You've brought back a true work of audio art!
Many thanks!
Depending on which cold beverage, my radios can sound better or worse 🤣
Very true.
Experience is something you get Just After you really need it,
and it is proportional to the value of the equipment ruined.
Just to name a few, the Krell Duo 300, the Spectral DMA 300, and the MBL 9011 are easily as powerful. The McIntosh 462, the Bryston 14B and the Rowland 825 are all far more powerful stereo amps. All are rated at least that amount into 2 ohms, most of them doubling their output at 4 and 2 ohms. The Boulder 3060 stereo amp however crushes all competition that I know with 900w at 8 ohms and 3000w at 2 ohms. Did you wonder about their mono amps? Their 3050 puts out 3000w at 8 ohms and an incredible 6000w at 2 ohms.
Thanks for sharing.
I got the AU20,000 have lower damper only 40
Me too
Foget the amp. The real story here is your wife getting it for you, or as the rest of say, just allowing it in the house.
Ya, I agree. She's one in a million that would tolerate my vintage audio addiction.
Yep!! The wife is high quality.. Like handmade Tokyo sansui!!
lab gruppen plm 20000q has 20,000 watts, that me seems to be more than the 600 watts this thing has
Time machine....2022 is not 1975....
Great work as usual! What would be your favorite amp/receiver in your opinion? I know this is probably a hard one to answer..
Thanks! That is hard to answer. Sometimes I'll be listening to certain equipment and think that's the perfect setup.....Then I'll hook up something else and I'll think the same thing.
@@vintageaudioaddict I totally get it!
Sir, First thank you for in depth narrative and component description. I have subscribed and watch your videos from time to time. I love the vintage audio and grew up in the cassette tape era. Now I own three Nakamichi cassette decks including Dragon, a RX 303 and RX202. Also a HK 491. Recently I paid quite a bit of money getting them cleaned and restored. I would love to learn how to work on them and your videos and detail description is very useful. I would love to learn more starting from the basic. The only request I would make is that if you can, please record the videos when you are working on an equipment like this one. Thank You again for such details.
So it's rubbish.. As impedance halves output needs to double. All seriously high end transistor amps do this like Krell. YAWN!!!
While serving in the Marine Corps and stationed on Okinawa, 1978/79, I purchased a whole rack of Pioneer esoteric stereo; including the Spec-1 preamp and the Spec-2 power amp. I went with Sansui SP-X11000 speakers. Those speakers have (2) 17" woofers, (2) 6" midrange, (2) 3x6" horn tweeters and (2) 1 1/2" super tweeters per side. These speakers are unique in their design, where each stereo side is separated into (2) cabinets to isolate the woofers. The crossover was located in one half, so there had to be an electrical connection. This was done, using an (8) pin vacuum tube socket and pins. Rubber feet on one cabinet fitted into recesses in the other, and the socket/pins connected when you sat one cabinet on top of the other. As far as I know, this particular model was never marketed in the states. I bought (2) pair of these speakers and powered them with the Pioneer Spec-2, 250wpc amp. Awesome system!
First of all thank you for your service. Wow! Amazing gear! Thanks so much for sharing.
Your my hero!!
get your hands on a Nakamichi 620 amp.. Rated at 100 watts but a tad underrated It blew away 300watt amps and still does..And it wouldn't put AR LST on its knees.. DAMM inefficient speaker
Essentially, it's a constant current amplifier. It's far from being the most powerful amplifier ever, though, given that we now have pro audio amplifiers capable of delivering 30KW into 1 Ohm loads. Great vid.
This takes me back to my teenage obsession with power amplifiers. This one and a Peavey 2600, both wrecked, were given to me by my grandfather's DJ bud (although I've always suspected my grandfather paid for them). I eventually repaired both and, since I haven't heard otherwise, they're still working fine, decades later.
Very cool! They will probably still be operating decades from now.
Oh my goodness, I have it's mate the CA-3000, quite a while ago, not sure what happened. Have been into this goofy hobby for about 50 years so I know a little bit, and High school had one of the best electronics courses at the time but this one has me stumped just no output. Have to admit I am more a vacuum tube guy, we had transistors in H.S. but we did not mess with them way back then too sensitive! And expensive!
You’re good instructor 👍 I love those explanations very helpful 👌

Glad you like them! Thanks a lot for watching.
I solid & own Ba5000 twins which I bring out a couple times a year to Wake my Maggies up.normal Amp is my Pass Labs 30 watt class A which does sound sweeter & smoother, but is fun to RIP Led Zepp -Pink Floyd thru them my Pass pre helps
Ive been doing Electronics repair particularly HiFi audio and Pro audio gear for 35 years and i can testify if you dont know what your doing dont dig into your favorite piece of gear as a first project find something cheap and try to fix it and i never let a unit leave my shop with more than 30MV offset . That Amp reminds me of working on G-33000 and 22000 receiver amp sections .
I have an AU-7500 in my desktop system... I love it. And despite the "rated" 32w p/c it'll blow me right out of my desk chair driving a pair of DALIs. Another one that will never be for sale... neither that nor the TU-7500 that came with it. Both NOS, checked/overhauled by me with BT added to the tuner to preserve/add function.
Beautiful job... well done, and thanks for taking the time.
PS: FWIW I cut my teeth in electronics building Radio Shack and Heathkit kits... back in the day, ya. Those were great learning, and great practice.
Subscribed, and cheers from Japan.
Cheers from the USA. Thanks so much for the kind words and the sub. Your AU-7500 is a wonderful integrated amp. Sansui made so many great products back in the day.
BEAUTIFUL AMP!!!....I have the baby brother, the BA-2000.
Sounds like there was a cooling thermal system had an issue.. I’m still watching
The bias transistors not being attached to the cooling fins is a definite red flag.. the fan probably was turning on.. possibly a thermal runaway occurrence.
I have a Yamaha A-1000 with those bias transistors on the cooling fins.. I replaced because I accidentally broke one with my cleaning cloth-I actually found original replacements, I went ahead and replaced the pair and adjusted the idle current but it was still in spec so only a minor adjustment
-I use a new soft paint brush now.. the cloth was a bad idea.
Yes, I chipped off some of that hideous black/brown glue that can turn conductive over time. the A1000 is an 1983 model but was virtually unused.. just dried out pots. I also have the A-1020 mosfet version that has an issue in the tone bypass switch.. not sure if it’s the switch itself.. it used to work find. I keep it turned off-no tone control off position doesn’t make noise.. while switching to the tone control position makes a crackling sound. It used to work if I’d hit it quickly to the on position.. it’s unusable now until i can work on the switch. It’s also very clean for its age-1985
You "could care less" How much less could you care? Sorry pet peeve, I could NOT care less, is the proper saying. Thanks for your videos. I am a Sansui fan.
Funny, how my 2 times 2 Watt amps are considered to be the best amps on sound quality. And even can blow the plaster of the ceiling. And how many Sansui amps are sold nowadays, the amp here forwarded, a lot of power, and no brains!
@@robertthurston6858 Well, I don't have horn speakers, there are plenty of speakers, highly quality like, who love simple amps. Most have paper cones.
Awesome video, like always. I have watched many of your videos over the last 3 years or so, but never seen one that shows how to search for an equivalent component such as a Vintage Transistor, since the vintage gear numbers are not made anymore, do you have a video that shows how to find vintage equivalent parts?
Thank you very much.
Was the output transformer a true transformer or an auto-transformer like McIntosh used? On Roger Russell's McIntosh page he explains why they used the auto-transformer, same reason, to keep a constant load on the output transistors but it also has another advantage. If an output transistor shorts to rail, the transformer is a very low DC resistance so it just blows the rail fuse - and reliably without counting on the DC resistance of the expensive speaker.
It's an auto-transformer. Rumor had it that Sansui copied McIntosh but I'm not sure.
I guarantee if you take a drink for every time, he says 45 years old , you will be drunker than a monkey.😂
Great job, beautiful piece.
Thank you very much!
I'm new here, . . and 3:00 mins in You sound like Sheldon Cooper
( but I digress ) seeking Wye white separates, . . .
Nice I like the tip on testing output transformers by running a low voltage through them. I have a massive HH V800 classic PA amp. Although it's clean enough for Hifi, if you need 800 watts, that is. Watching you work away here reminds me of all the dirt that was inside that when I first got it. It was full!
Thanks for sharing and for watching.
Shooting at McIntosh, output transformers potted.Better than most ???
Vintage audio gear has turned into a racket. Dealers want $2k for something like this, and it still has to be restored or re-re-re-restored. I miss the Golden Age - the 80's and 90's - when no one had a clue and you could get pieces like this for $100 because "it's broke".
The vintage audio equipment has got pretty expensive. With that being said if you can find a BA-5000 for 2K buy it. You can trade it for a good used car. LOL.
Picked up a Marantz 2325 for 100 bucks
I’ll keep my Carver 500t
I have some carver equipment. I've always liked it.
So awesome how you go through your method of restoration. How do you figure out what to use for obsolete transistors much less double up on some? Mahalo for another awesome video
Thanks so much for your kind words and for watching. Being a hobbyist I've learned mostly from folks out here on the net.
Hello, i want to say, i love all your videos, i am 55 and i remember what my friends brother had and back then he had a technics SA 1000, man that thing kicked ass at 330 watts per channel, and his buddy had a Sansui G 33000 and it kicked out 300 watts per channel, these things sounded great it was like they had a life of their own, todays stuff is not at all like that, anyway, again, i really enjoy your vids and i watch all of them , thanks for all the education, between you and xraytony and mr carlsons lab, we all get great education and memories of the great audio world of the past, thank you.
Thanks for sharing. Man, I've never even seen a SA-1000 or G-33000. I'd love to have either in my collection. For many of us this equipment brings back good memories. Thank you for watching and for the kind words.
What a great video and better at teaching than anything I can remember.
Super thanks
Watched one of your videos, started watching this one too but had to stop as I couldn't take the endless repetition. Basically, you repeat the same things in every video which gets tiring to listen to. Sorry to be honest.
Just saying the model number puts tingles down my spine. Nothing comes close!
This interested the hell out of me I can’t believe it had that much power per channel for the age and it looked great at the end great job I would love to own this myself I would have loved to hear it played
That is one beautiful apm.
Thanks for taking the time to make the video and share it.... Really enjoyed.
Your welcome and thank you so much for watching.
What's your method for cleaning up the back sides of the boards?
Usually IPA(Isopropyl Alcohol) and a small brush. I've never had an issue with it but I'd try a small spot and see how it works for you.

Thanks so much and good luck with your projects!
Boy your lucky to have one of these amps!! They still bring $$$$$ if you can find one, and boy they do sound nice.
The BA-5000 is one of the classic's and yes, I am lucky to own her.
I was lucky enough to to be a Sansui dealer back in the 70’s…I had the opportunity to take home every model in the Definition Series. The BA5000 was driving a pair of Cerwin Vega 15T’s (103 db/1 Watt/1 meter)…Wow!….. I even painted my Sansui Sound Room the distinctive maroon colour of the amplifier covers …it’s a beast…best amplifier I ever owned….
Thanks for sharing!
You are wise
Available for sale???
@@stellarecosystems8228 I wish!!! I sold it over 40 years ago ….oops!!! Good luck on your quest!
@@pisbee i wasnt even born 40 years back sir 😀
I remember an old Phase Linear power amp I owned, it literally scared me every time I switched it on and I swear the ceiling light dimmed each time! It sounded majestic but they did have a the nickname, Flame Linear😳😊
That along with the Crown DC series were notorious speaker eaters.
Yes, vintage audio equipment did/does have some downsides. If you keep the old equipment maintained your chance of disaster is reduced but never eliminated.
@@vintageaudioaddict there’s a dandy DC protection board available for the Phase Linear amps from watts abundant to solve that issue. Beauty BA-5000 btw... I’ve got an AU-7900 and it sounds great too.
That ishow I feel about my Phillips 572/578 combo, permanent n.f.s
Thanks for watching!
That amp is clearly a McIntosh wannabee it's pretty clear they went for a McIntosh look , and even design (using transformer on the outputs)
I wonder how it sounds in comparison
The closest Mac amplifier I have to my Sansui BA-5000 is a 2205. I can say those two sound a bit different. Not sure if I prefer one over the other.
Try again.. Nothing..... Nothing beats handmade Tokyo quality
Wonderful Video
Thank you very much!
Chris, I always enjoy your videos. Your experience and willingness to share your knowledge is priceless.
I see your go-to choice for power supply caps are Nichicon PW series. I've used them when I can.
Curious to know what your go to cap choices are for bipolar, signal path and other general use caps?
Oh....also, I never see such finds like you have. That is truly impressive
Thanks so much for the kind words. I truly appreciate it. As far as the capacitors go for me I've found that I can't tell the difference in sound between a soni-cap and a Nichicon or a Panasonic in the signal path for example. I do stay away from the no name brands because name brands are not very expensive.

Very nice results! I was stationed in Japan and asked to go there for the audio equipment. While in the Air Force I bought a few systems and really didn't realize how substantial audio was at the time, 1973-1974 which for anyone out there that was the Golden Era in audio for Japan. The exchange rate was absurd, 400 yen to the dollar where today it is about 90 yen to the dollar. Sansui, Akai, Pioneer, Teac and others were the big boys of the day and they made a lot of the audio equipment at great prices!! A kid in candy land.
Thanks so much for sharing. So much great back in the day and yes the exchange rate didn't hurt. Thank you also for your service.
Oh the joy! Even without knowing the future having the opportunity to shop for and find stereo equipment at prices that didn’t disqualify you from being as ridiculous as you want. I had that opportunity in the Philippines while on the USS Constellation in 1976. I chose from a slightly smaller sampling than you and decided on the Sansui 9090 db along with a techniques sl-1200 turntable and 4 Sansui sp-1500 speakers. I was almost broke when I remembered my then young wife was interested in some furniture. At the very last moment I borrowed some money and had a couple of kinda ugly furniture items thrown onto the Connie. So nice they went with me to San Diego and then shipped to Whidbey Is. Wa. I didn’t particularly care for military life BUT my last year I certainly enjoyed and over the years looking back at that cruise with fond memories. Just for the record I don’t have that glorious set up anymore and I also jettisoned the wife but as I noted the memories are still crystal clear. Take Care
Most powerful. No i don't thing so. Maybe most powerful HiFi amplifier. Still cool amp tho. Mmmm. All then MOSFETs
Thanks for watching!
I found my center piece today a Yamaha B-2 amplifier and T-1 tuner from 1978 at estate sale. It was the last day of the sale and an hour before shutting down. The sticker price was $1450 and the wife of the deceased said I make you a deal and I paid $300. She wanted me to take it as she felt I would cherish it as her husband did. She said several men were resellers that told her they would come back later. The amp obviously had been sitting for years. It was dirty inside and out. It needed a lot of cleaning especially the pots. I spent several hours cleaning and inspecting. I finally plugged it in and power! The meters glowed and the music was sweet via vintage Yamaha NS-670 speakers also purchased that day. It has now replaced my Yamaha CR-2040 that I just obtained a week before at an estate sale. I enjoy your commentary! 🙂
great video, great amp. top stuff i enjoyed watching this :)
Much appreciated!
Would you possibly be interested in restoring my Rotel 1412 amp that just blew up again? I had someone fix it before and it blew up again... I could ship it to you and you could make a video for your channel, I'd be happy to compensate you for whatever cost. If that's something you'd be willing to do please let me know, we could exchange contact info and make something happen, I do NOT trust the guy I took it to anymore...
First of all I'm really sorry about the issues with your 1412. It's a great piece of gear. I don't work on other peoples equipment. One of the main reasons is because of your experiences. I'd just hate to work on someone's precious audio equipment and then find out that it died on them. It would make me think maybe I missed something even if I didn't. I'm not professionally trained. I'm a hobbyist that learned to repair and restore old audio equipment on my own.
My favorite Amplifier Sir, I never had it but i love it so i took circuit diagram and print all PCBs by hand , Wound power transformer, connected all together and made it my self with locally available parts... definitely not a professional standard but satisfy myself...I wish may be i am able to purchase it some day.
Do you know anything about the Muse Model One Hundred Fifty? I have 2 of them. There's a video showing the components on my channel.
No, I've never seen the Muse's. I'll check them out on your channel.

WOW -WOW-WOW
She's a beast.
There are lots of amplifiers that produce more than 300W.
In 2022 ya....1975..uh.....no
Congratulations for the nice equipment and restoration work done! You work very professionally, with passion and meticulously.
Thank you very much!
Better than TOTL Nikko or Luxman?
Try an Onkyo Grand Integra M-510
Any where would this be available for sale?
Nice
Thank You!
Nice but the Bose 1801 is more powerfull , and also alot of S-A amps ar bigger then this sansui , its nice not the most powerfull
That is a monster. What a gem,you are very fortunate. Thanks for the great videos.
Yes, thanks for watching!
Looks Fantastic ! You did an excellent job. I have an old Marantz 2325 and it’s old and still rocks but it’s time frame a up-date. It pushes a Pair of Klipsch K-Horns and another pair of Belles Kilpsch Speakers, early La s callas ! It Rocks but last year it burned a bulb out. It is very clean and everything is Walnut , speaks and Marantz look Beautiful ! I’ve used them for over thirty years . Quality! As everything like me it’s old and I’m sure it could be better. The new parts would probably make sound much better. It’s my keep until I die pieces. The combination is Great still push goosebumps on me. I feel like you do, and I’m in my 60’s now still Love it all ! It would cost a small fortune to get that much music today and the quality probably isn’t going to be as good or any better . Yeah, like you I’m set in what I want ! I’m old school and have always remembered to Don’t fix something that’s not broken ! Plus I would want to deliver my stereo and not ship ! Honesty today is much harder to find. I’ve read up and watched videos about the up date. There are packages with everything you need available for it and many other valuable old stereos. I can’t do it but I will find someone and take a trip ! Hand delivery. I started with a Sansui 7700 in the 70’s Marantz tuner . Wish I had kept that amp ! Had the big Sansui receiver and wish I had really kept it ! Now they are thousands of dollars ! Keep it up , beautiful work !
Thank you very much, Sir.
Didn't hear the amp at all,you gotta know when to talk and when not to
Hi where did you find your fuse lamps?
Never heard of it,
Lot Of Wires Compared With Today Machines .... But Sansui Sound Was Unbeatable 💎
...I assume the "BA" stands for Bad Ass.
Excellent Work Sir

At this point in the video, I cannot stress enough: build a Dim Light Bulb Tester! That way, if there's a messed up bridge rectifier or blown fuse, the DUT won't short and blow up.
Later in the video my first power up was with a dim bulb tester along with a variac. Thanks for watching.
@@vintageaudioaddict I just got there. I actually commented before I watched the entire video. Love your work and you're inspiring me to service a lot of vintage audio stuff. I'm actually working on a cassette deck right now.
I only commented that because like an idiot, I powered on the deck without building a dim bulb tester first. I could've been in trouble if the Rectifier shorted.
Fantastic work very good. Thanks for sharing
Thank you! Cheers!
