Technics SE 9600P Power Amplifier - Can Beat Pioneer Marantz Sansui. Repair Restoration Testing

[@matthewgolterman4570]

Thank you sir.. So many of the other folks in your space annotate/edit their vids to more fit into KZbins preferential algorithms. I appreciate you giving us 2 hours of your time and letting us see it all.

[@vintageaudioaddict]

So nice of you. Thank you for watching.

[@williamjones4483]

While your sentiment is appreciated, there is another viewpoint, one that says many people don't have the time (or patience) to sit around for that length of time to watch a video. I am into computers in a big way and there is another KZbinr that shall remain nameless that will make videos sometimes four hours or longer. Videos of that nature become tedious to watch, especially if the person just drones on and on. At the same time I don't like them so short as to be useless. Having said that, I believe that is why many videos are short.

[@1sostatic]

Happy to share a trick from a UK restorer ... the facia ... take high res images of the original screenprint, logos, pot scales, etc and rebuild the facia in photoshop 1:1 . Take the original coat off the facia and all the sscratches out with orbital sander... heat the clean aluminium facia to 40°C. fire a dusting of primer at it, then colour coat matching the original .... take it to a screenprinter.

[@scottfra]

Really appreciate what you put into these videos. And especially appreciate all the background on the founding and evolution of the brands. Well done!

[@vintageaudioaddict]

Glad you like them! Thank you so much for your kind words.

[@andyr8812]

It's sad to see that some people don't appreciate what they have, and don't take care of the equipment they own. This is definitely a great amplifier that deserve more lifetime. Great job!

[@vintageaudioaddict]

Thank you so much.

[@samiam9059]

Most are not interested in true High Fidelity listening whatsoever these days. Back then we were obsessed with excellent gear and speakers. Today people listen to MP3 recordings which are compressed 10x and 12x and multi sampled as low as 128? Like people using crappy cellphone cameras over a good camera. They just don't care today..

[@jaismohamad1497]

I'm 72. Just came across this. It brought tears to my eyes. I had one like that after scrimping and saving matched with pioneer speakers. I thought that it will be my last amp/system. Sadly when I was away it was stolen. Only the speakers were left. Sid buy any good system after that as I got married and money was tight. That was the best I ever bought .

[@vintageaudioaddict]

Thanks so much for sharing. Sorry that she was stolen. Money was tight on my Pizza Hut salary back in the day also so I wasn't able to afford an amp like this one.

[@jaismohamad1497]

@@vintageaudioaddict I was a school teacher with meager pay. I was also an amateur musician. Most days I had a meal once a day. I cooked myself. So losing a great sounding amp like that really hurts. Let bygones be bygones. You're doing a good job bringing those great amps back to life. Keep it up and stay healthy always.

[@craigm.9070]

Thank you for walking us through the restoration of this beast. I've always wondered what the person whose SSAN is etched in the back panel would think if they could see their equipment all these years later still performing at or near peak levels with just a little love after 35-40 years. It looked like some real thought went into the design phase when it came to technician access and component locations for maintenance. It sounds very good with just your CD player. Enjoy!

[@vintageaudioaddict]

You are very welcome. Thank you for watching. The vintage audio equipment was engineered/built to a standard that is rare to find in electronics today. She's really a great sounding amp.

[@NasaraThePoet]

Thank you for walking us through every detail it really helps to demystify the process. I would also add that the brand history segments are a nice touch. 👌🏾

[@Every_Day_Adventure]

I remember drooling over these in the Stereo Review magazine. I always circled the reader service number on the card on the back to get the free brochure. My first integrated amp was a Techniques SU-8055.

[@hardball107]

Thanks' for the video. Love the detail and explanations. I have a 20'x20' room filled with vintage radio's, amps, turntables and receiver's. In my experience, sticky? Spilled beer. I started collecting in the mid 70's. Never threw anything away and collected any radio I cleaned out of someone's basement. That stuff sat around for over 20 years, wife crabbing about the wasted space and all. Then came the internet, parts, schematic's and video's along with shops that specialized in restorations appeared like magic. I'm still going through my Sherwood, McIntosh and Scott equipment to name a few along with the GE, Carlson and whatever radios I have 30 years later and guess what ? My daughter just hit me up for a Sansui receiver, a B&O liner drive turntable and a set of EV studio monitors after raiding my vinyl collection, glad she's a fan of the sound. Now she's eyeballing a Kent floor standing radio and an old Seeburg juke box for her basement.

[@vintageaudioaddict]

Your welcome and thanks for sharing. Great story! Ya, beers a good guess. It's great that you have had your equipment for so many years and that you have a daughter who is interested in the gear. This equipment will be running long after you and I are gone so younger people like your daughter will keep it going for the next generation.

[@TSUTENKAKU007]

Thank you for this presentation. Yes, Technics came out with very good equipments back. I think this amplifier had a matching preamplifier, same color and that reel to reel tape deck as well. There were also one or two sets of speakers to match this amplifier came out around that time. They were all good. I had SL-1200 turntable in 1974. Some Sansui have push in pull out circuit board mounting which makes easy to repair, just like this one.

[@vintageaudioaddict]

You are welcome! Thank you for watching. The matching preamp is the SU-9600. I don't have that one in my collection but I'd like to find one some day. Technics made a lot of great audio gear back in the day.

You are well spoken, dedicated, sensible, and I love the history parts. Keep up the great work good Sir, I'll likely skip some of the more technical parts because I am not that much of a tech, but at the same time I watch interesting parts because I love watching folks work in a field they have a passion for (and I almost always learn something). Over the years I had several receivers by Technics and I have and old SUV-76 that needs a power switch in my stack of broken things that one day might find some love from somebody as dedicated as you in keeping these beauties alive.

Hi David, your welcome and thank you for sharing. It's great that you still have your G7500 after all of these years. I still have my Sansui TU-717 tuner that I purchased in the late 70's. This vintage gear brings back some great memories.

[@douglaspage2398]

I miss the old stereos. The pioneers were good, my cousin's parents had one, and when they were gone he would crank it up, and before they got home we would have to tighten the screws on the trailer. But the best one I ever heard was an old Macintosh that I bought at a garage sale for $20. It took me a couple of years to find a set of speakers that could handle it, it would throw the breakers on most at half volume, unbelievable sound, and the thing still had tubes. I gave it to my nephew when I moved into an apartment, and he used it for years until it quit. Sadly, he threw it away. I just saw one on E-Bay a while back, non working...... It sold for $3,500.

[@muppetpaster]

I still have this amp with the complete set....With for example the SU9600 and the ST9600 and the SL1000R turntable, which now goes for I think about 20K plus dollars....The unit you're restoring is a BEAST of an amp...

[@dalemettee1147]

In the 70's, I got a new RTR recorder. The US 1500. Absolutely the best sounding unit, for the money, I ever heard. I liked it so much, I bought another one.

[@vintageaudioaddict]

Thanks for sharing! Technics did make top notch open reel decks. I've never owned a Technics RTR but I hope to one day.

[@socksumi]

I used to own the Technics SU8600 a beautiful integrated amp from the same era as this one. It sounded smooth and transparent with excellent build. The phono stage was particularly excellent. It used a massive multiple position click stop Alps pot for the volume control. That part alone would set you back close to $300 now.

@@vintageaudioaddict Many thanks for this great video and walkthrough, I would like to ask you a question regarding Vintage power amplifier I have bought last year, well last year I was lucky guy ! I have bought ADCOM GFA 555 MK2 this power amp is/was built from the 90's 90-95 , I have bought it from a guy which never opened it from the original box , it was originally manufactory sealed box, so it was stored in a closet for more then 25 years. When I got it I connect it to mains and removed the top cover to look inside and checked the bias , of course all is good and new, and it is sound incredibly amazing. So what I want to ask you is should I replaced all the electrolytic caps ? should I be worried about if they will not be replaced , do they are in good shape as we dill of course with new amp that never been used all this years it was stored ? Thanks in advance and continue your great Job ❤👍

Great video! YES, working with an old, even beat up, amplifier is just tons of fun. Yes replace all the electrolytic capacitors. I recently picked up a classic Soundcraftsmen A5002 (250 WPC RMS @ 8 ohms, 400 WPC @ 4 ohms) that does not work. The faceplate paint is bad, someone has done some not so handy "handy work" with taped together wires etc. and some burnt power resisters but this amp should be a straight forward fix and put any wiring back to factory spec. . No matter, I can fix it, and it will work as good as new. Even though it isn't in good cosmetic condition, I will enjoy using regardless it does not look mint. I will use it with my other Souncraftsmen preamp,Souncraftsmen equalizer, Souncraftsmen tuner, I already have.

[@fflynnful]

The ribbon connector makes it easy to work on, but it's a failure point. Maybe it's why they apparently glued it in place. :) I've been working on this type of stuff since mid 70s. Ever here of United Radio in Syracuse? Great video, it's nice that you included the video from Matsushita.

[@solitaire5142]

Nice video. Its been my experience restoring vintage gear that PCB`s that are easily serviceable which employ edge connectors or other multi-pin connectors pose a greater threat than failing capacitors and also should be cleaned with a good quality contact cleaner. When I come across T03 output devices that are not easily accessible, a telescopic magnet tool aids greatly in removing and replacing them.

Technics Audio had been quite underrated in the 70s up to End 80s. Presumably they didn't pay sufficiant for adverts in the Audio Magazins. They invented a lot highly interesting Products in that area of technology. Technics is back since a couple of years now; possibly because the Vinyl Revival. Finally I got quite a lot of Technics collections, where my first Audio had been SU 8022k ST 8022k, SL Q2 and RS M63 all running still fine without any Service.

I remember having this amplifier and its matching preamp in my shop. It was extremely hard to sell because it looked like a PA amplifier. I always thought its sound was under whelming. Not poor by any standards, but other amplifiers, even other Technics amplifiers just had the edge on performance. Many at half the cost.

[@PeterMilanovski]

I realise that this video is 2 years old now, it's rare to see someone else who goes up in capacitor voltage rating. I see it happening on rare occasions but I don't see it happening often enough.... I don't believe that every single capacitor should be replaced with a higher voltage equivalent but at the same time it doesn't hurt anything if you do. I tend to test and measure the old capacitors to see if they have had a hard life and make sure that those ones get a higher voltage equivalent... Regarding using film capacitors on the input, I have seen on one occasion over on X-ray Tony B's channel where he replaced electrolytic capacitors on the input with film capacitors and found that the sound had changed which he could hear and it showed up on his oscilloscope doing a frequency sweep! So in that case I would recommend doing a frequency sweep and checking to make sure that the amplifier can do the frequency range it's specified to do, just to be on the safe side! As for the heatsinks on this amplifier, I would have preferred to see them removed and washed clean, I think that years of heat would have a baked layer of something on them which possibly invisible to the eye, might be adding a layer of insulation.... That amplifier has an incredible 1kw of power consumption rating which tells me that this thing will get pretty hot when putting out some serious power! You would want it to be able to dissipate heat as efficiently as possible! Also, I would have liked to see some deoxit used on the transistor sockets, sometimes they get dirty and cause problems with intermittent connection's kinda like with vacuum tube sockets.... Apart from that, this was a great restoration, the amplifier design is excellent for service work...

[@aussierob7177]

When i was looking for a new pair of speakers in 1984, i went into one of the hi fi retail shops in Sydney and they were demonstrating a pair of Rogers Studio 1 speakers. I think the amplifier driving them was a Pioneer SM 83 Tube stereo integrated. The speakers sounded fantastic, so i bought a pair. I did not buy the amp, but in retrospect, i wish i had.

[@vintageaudioaddict]

Thanks for sharing and for watching. Rogers made some great speakers back in the day.

[@g0fvt]

Excellent video, a lovely amplifier too, though I would be wanting to do something about that fascia. Some of the 1970s audio equipment has not been surpassed, generous power supplies too relative to modern gear.

Thanks for commenting. I love hifiengine.com but I never leave reviews.

[@morrisonAV]

Watched the entire video! Took me most of an afternoon to do so, but well worth it. I do have a couple questions: 1. What was the middle output transistor that looked like its metal cover was missing? You stopped the video right before you came to it. Also, since you have the outputs all removed for thermal compound renewal, do you ever test them to see if they are still in spec. Also should be sure to tell newbies to NOT use their old CPU thermal grease on those outputs. 2. Why didn't you show us beginners how to use solder braid? Not everyone can afford a vacuum solder sucker gun like the Hakko. Thanks again for an enjoyable video.

[@vintageaudioaddict]

Your welcome and thank you for watching. 1. - I think you are probably talking about the thermistor that will disconnect the outputs if the amps heatsink temperature gets to high. 2- No, I never test them unless I have an issue. I do bench test after I do a repair/restoration so that will check them out well. 3.- Well, if you have your amplifier apart and you are using CPU compound, you probably should have never started the project. 4.- I am terrible with using solder braid and I'm not the one to teach anyone about that.

[@matthuston1767]

Hello. Nice to come across your channel. I’m a hard working combat vet. At the moment have some financial troubles my wife and I both work full time but with the three kids and past poor decisions by me left us just making ends meet. Long story a little shorter. I was given a Nikko beta and Alpha 220. I had my hafler eq hooked up and my 5 year old decided to play with the eq and it blew my amp. It popped the fuse so I replaced it and powered it up fuse blew and board smoked. Just looking for some advice. I live in PA I won’t throw it away and I still use the beta pre. I just want it fixed or want to get a trade so it can live on. It was a great amp.

[@vintageaudioaddict]

Sorry to hear about your issues. I would do a google search for "vintage audio repair" or "stereo repair" and see if there is someone in your area that can help you out. There is really no way to fix the issue without a tech taking a look.

[@johnproctor464]

Just ran across you're channel. Glad I did. Nice work from someone else who likes to fix everything I run across that doesn't work. Troubleshooting the drivers - make board extender to raise the board up where you can get to it.

Hi great videos and congratulations for your work Personally when i see open frame trimmers i try to replace them with multiturn sealed ones ... they are more reliable and allow for a more precise bias/dc offset setting. i use a little brush for applying the thermal paste evenly Kind regards, gino

[@vintageaudioaddict]

Hi Gino, thank you for watching. Those are good tips about the trimmers and thermal paste.

@@vintageaudioaddict Thank you ! i have to tell the whole story I had a very nice Nikko Alpha II old power amp purchased after reading great things about it One channel was not working properly I opened it and even if i am everything but an expert i discovered that two bjt drivers on the board of the bad channel had been replaced with wrong transistors ! like pnp in place of npn ! an unesplicable mistake indeed I bought the new bjts, replaced the caps, the trimmers and the boards looked just fine Then i missed the boards ! i had a moving at that time and i was in a bad moment The rest of the amp ended in the trash bean That was a very nice power amp indeed The one channel working had a clean and powerful sound that i liked very much So i have nothing to teach to anyone really I will try to improve when i will have the time Thanks again and kind regards, gino

I'm glad that you enjoyed it. Thank you so much for watching.

Great video, great work. Really respect your passion for bringing back to life what others will put at the curb. Please do a long rebuild video for the Bose Spatial Control Receiver 🙂

[@vintageaudioaddict]

Thank you for your kind words. You know......That's a good suggestion about the Bose receiver that I have in my collection.

[@jedi_mapperp4073]

@@vintageaudioaddict The SCR innards are unique. The architecture is unlike a typical receiver. Even the way it’s turned on and off is unique. The built in 901 equalizer is also a challenge to access (but what do I know…I’m hoping to follow your video to rebuild mine).

[@CEG3RD]

My first video of yours I've watched. I enjoyed the process and the way you edited it. I was a little disappointed you didn't make more of an effort to clean it up. I was looking forward to seeing maybe you even doing some painting that didn't happen, either. I didn't agree that it looked good as is. In the end it's the output .... still. aesthetics matter, too. Some people look at older items and call degradation patina, which sometimes makes me chuckle. Learned some things watching a good video, though.

Thanks for watching and sharing your viewpoint.

I like u and 12voltvids u guys are so informative i love anything electronic especially the older ones the news seem to shut off bc of the circuit protection older ones played until u blew the speakers

I love my Onkyo Integra dual mono block amp. It’s beautiful.

[@vintageaudioaddict]

Onkyo made some wonderful audio gear back in the day.

[@humminglake]

Love your videos. Thanks for the effort and fine work!

[@bdc211]

technics su-v8 was one of the best sounding amps i ever had... beautiful as well..

[@vintageaudioaddict]

Technics made some great gear back in the day.

[@LeoShimm]

This guy is excellent !! Love to watch his all video, although I may not do anything similar try, but can get lot of knowledge out of his video !!

[@vintageaudioaddict]

I appreciate that! Thanks for watching.

[@EsotericArctos]

I can understand the Input On/Off under some circumstances. It would mean the amp stays warm, so stays more stable. Also means, in the event of a quick change over in a public system, you are going to have minimal downtime and less chanse of pops through the speakers if something had to be changed mid show or something. On that note, if a peamp or input device fails in a destructive way, you can quickly isolate it and protect the power amp. Probably not really something you'd use in a home environment.

Fantastic video. As a big Technics fan, I really enjoyed the corporate video.

[@vintageaudioaddict]

Glad you enjoyed it! Thanks a lot for watching.

[@larsgunnarsson260]

Thank you very much for your deep and serious walk-through of this excellent equipment❤!

[@robertdavis5714]

That was the thing, metal engrave (on front) either name or SS #. I remember buying my 1st stereo receiver in 1979 and actually considered doing that. I dread seeing those light color purple Elec. Caps.

[@vintageaudioaddict]

Thanks for sharing and for watching.

Excellent video, thanks for taking the time to put this together!

Your welcome. Glad you enjoyed it!

[@per-henrikpersson1884]

Great video, Great work and workmanship, and a REAL Jewel of Power Amplifier. I want 6 or 8 of them to my Home Cinema System and give my subwoofers to someona that NEEDS them. A fantastic video.

[@vintageaudioaddict]

Thank you very much! I appreciate your kind words.

[@robertzemko6590]

In early 1978 as a teenager just getting interested in gear I convinced my dad to pick up a new Technics SA 5570 Receiver 85 watts/channel as it was on sale for $429 still a lot of money back then but much cheaper than Marantz or Sansui equivalent here in Canada. Dad still has the receiver and we/he had many great years with it. Technics was a much more reasonably priced brand that could take on the best of them.

[@vintageaudioaddict]

Thanks for sharing and for watching. Technics made some great vintage audio equipment. It's so wonderful that you still have the SA 5570 still in the family! I still have some of my original pieces from the 70's also. Sadly not all of them.

[@gilbertwashburn7095]
