วีดีโอ

Great information and presented very well. Thank you!!

Just got the very first sansui solid state sold in america for a steal. If you are aware of any suppliers for reliable germanium bjt equivalents , let me know. I can't really trust eBay for something that iffy.

I had a Pioneer just like that many years ago, it had 80 watts and the front panel here is exactly as I remember mine. The blue meters were wonderful, unfortunately it died after many years of great service

Sup man. Qiuck one. Got one of these from a friend. restored it and gave it an agressive wash like you did on the other vid. And had to scrub it with ipl and a toothbrush as there was stuff that just wouldnt come off. Anyway How much do you think its worth. The guys on ebay selling the lower or 7800 models for insane prices. So dont want to list it for an unrealistic expectation. Thanks in advance.

Love the little National too ❤

Hey bro!! Great channel

That U67 on my voice smokes that U87 on my voice and I mean smokes that U87 no thank U67 for the win for me all day every day and know the same height. This is the real McCoy.

I have this amp, and its time for a total re-cap

Hi, I'm rebuilding my friends. krell, do you have the service manal

Mine has a blowed fuse, on the fuse it said socv5a. Can you please tell me the correct fuse? Thank you in advance!

Che differenza passa tra piooner sa706 e sa 708 ?

They are stunning amps. I have had mine from new. Just love the Pioneer kit of the 80's

Great amp! I prefer the sa606 though

Hi! Nice cleaning method, I will do it with some other boards, if the transformer is far away! I have a Naim 32.5 and Nap 180, modded following the instructions of the pfm forum, and I am very very pleased, the upgrades are massive, but... I'd like to have some more control for my Mark & Daniel Maximus Ruby speakers. 82db. These speakers will stay, I love them. The sound of the Naims are very fluid and soooo musical, hights, lows, everything is satisfatory. I thought that the Musical Fidelity P180 could solve my problem of "more drive" without a loss in quality. anotherv thing : I wonder if you changed the electrolytics of your integrated, other than changing some resistors for the (I think), Vishay, RN type. Anyway, I can use the P180 with my "upgraded" Naim 32.5 if it sounds good, or just use the Musical Fidelity with my Brooklyn dac, using the dac as a preamp. Your integrated only has a vol controil, not a real preamp, so it will work well without the Naim. I only want a litle bit more control, the NAP180 has some, but I'd like to feel that he has some more than needed. Do you think that this is a good solution ? Does it make sense to you? Thank you very much for the videos ! Francisco

Great video. How do you get the amp so clean?

Would love to see more from you again. You have done some really interesting amp repairs so far!

Un amplificador excelente yo lo tengo y es sencillamente espectacular,lo recomiendo

Hey man what detergent did u use to clean up the Amp?

the sweeps on the 3020.... mine doesn't do that. I would have a suspicion that someone has swapped out some caps in the audio path &- possibly thinking it was a good idea, based on how one might install bigger filter caps in a PSU, replaced them with larger values, when that hump at 125Hz had been designed out.... just an idea. could also be caps going bad.... but the symmettry of it....🤔

Sweet looking amp and I own one so know how good they sound. BTW, nice trick with the meter lamps. I sourced standard incandescent replacements and was trying to figure out how to get that nice warm green glow.

Wonderful review! Imagine my delight tonight watching this video after picking up a fully functioning set of the following for $80 not knowing if they were completely worth it: Pioneer tuner TX 608 Amplifier SA-708 Dynamic Processor RG-2 Reverberation Processor SR-303 Graphic Equalizer SG-9800 Tape Deck F-650

lovely and informative! great bit of vintage HIFI history. looking forward to more.

So i have the exact same amp on my bench , there are absolutely no instructions online on how to bias this thing. The schematic shows 2x10w resistors when in fact there are none. Can you shed some light? I read a diyaudio thread talking about biasing this thing for 50ma across the 10 ohm resistors that simply from my view unless i'm blind aren't there.Any help is appreciated.

I have one of these that I picked up cheap at a garage type sale about 10 years ago. ($20 US) It was not working so started with those wire-wrapped terminals... and presto... PERFECT! Still working VERY well today. The Spec-1 preamp was not so lucky. Still not working but looks great on the shelf. (another $20) That one powers up but no signal passing through on either channel.

Another nice piece of gear on your desk! Thanks

Great vid, lots of informative information.

Thanks Dewald, I am a huge Luxman fan, great stuff.

Lovely amplifier and great to hear your thoughts on it! I know Tim Paravicini was lead designer for Luxman's MB3045 monoblocks and I have an A3600 Luxkit (MQ3600 Luxman), which was a cut-down stereo version. Both used the exotic 8045G triodes (pins 3 and 4 internally wired together) and 6240G driver/phase inverter tubes in a LTP.

what a shite job.

Hair drier

I am planning on getting a solid entertainment table because I would like stack it with amplifiers such as this ones. NO television

Please add a voice over to this video, your content seems to be very informative. Keep it up. 👍🏼👏🏼

Excellent video with clear and concise explanations. A lovely preamp to boot👍🏼

Hi i got the same one...still working good after 40y...luv the pioneer quality!! ;o) grtz from belgium!

Hitano is sucks

Hey Mr Dewald, I have a Revox a740 and a b740 and really want the lights on both vu meters replaced and also on my b740 the right side vu meter isn’t working.

I just bought an M-77. I'm glad I watched your vid I learned quite a bit. Thanks

it's a mk2. left hand guide is fixed on a mk1, & also the port where the VU meters poke through the front panel is undivided, where the mk2 & later have that narrow post between them. there's other stuff to do with the finish on the fold-down tape cover & internally...

My right meter isnt working advice please? I have an M-77. Thank you

Hello, could I ask what kind of led you have installed in the VU meters ? I think the voltage is 63 volts or so in the bulbs and I would like to replace the original filaments with led . Thank you very much for that and for the good video. Cheers, jack from France

I enjoy watching your videos. Thank you for sharing.

Are there any major differences between this model and the SA 608 model other than lower power (45w)?

Hi, nice video! I was looking for something like this. One question, maybe stupid, but I don't know much about electronics.. After unplugging, how long should you wait for the electrolytes to discharge?

Oh the smell when they go off... These smoke bombs are in everything a couple of decades old over here, and also inside Schaffner filtered IEC mains inlets. The mains inlets were quite popular worldwide. Greetings from Sweden :)

I believe those output transistors are actually from the Japanese Fuji Electric. I wonder if the MT200 Sanken transistors like 2SC3264 would fit. Still obsolete, but much more recently.

I have the Pioneer Spec. 1 & Spec 2, and the sound from the left channel is way softer than the right channel. What do you think the problem maybe? It used to work after a few minuets but has gradually gotten worse. All connections are fine.

Sería factible conseguir el folleto instructivo y el plano del modrl SA-708, gracias

Does this amp sound better than the new line of Pioneer like A 616 and 717. because I like vintage amps and receivers and I'm thinking to change my A 717 for one of those.

excellent work dude. HiFi jewellery at its best. you really show your love for these beautiful pieces. For me they are like the good handmade wristwatches, say Patek Philippe or Vacheron Constantin, truly art pieces which are made to be enjoyed by generations.
