Sony TAN-8550 VFET Power Amplifier Restoration and Overhaul
In this video, I walk through the entire restoration and repair process of this stunning Sony TAN-8550. This is the second video in a two part series which focuses on the Sony TAE-8450 preamplifier and this Sony TAN-8550 power amplifier.
This amplifier needed an extremely comprehensive restoration and overhaul to get it to function better than it was new, for decades to come. Almost every component inside of this amplifier was replaced to assure long term stability and efficiency. After it had been worked on by an idiot with zero respect or knowledge of how to restore a piece of gear properly, I had to undo damage done to many areas in this amplifier. Also done was a retrofit of a new IEC ...

Sony TAE-8450 High End Preamplifier Restoration
Просмотров 13 тыс.Год назад
In this video, I completely restore a gorgeous Sony TAE-8450 Preamplifier. This is the first of a two part series, which will also include the venerable Sony TAN-8550 VFET power amplifier. This was a very fun piece to work on, as Sony made it as service-friendly as possible. Most of the circuit boards are modular, making removal and installation a piece of cake. The internal wiring is also as n...

Here is a quick demo of the visually and sonically stunning Kyocera A-910 integrated amplifier. I finished a very comprehensive restoration of this piece a little less than a year ago, and I figured it was time to share a video of it in action before selling. This is one of Kyocera's / Cybernet's statement pieces from the mid to late 80's, and it exudes quality from top to bottom. The gunmetal ...
Sansui AU-717 Integrated Amplifier Restoration
Просмотров 167 тыс.Год назад
In this video, I tackle a beautiful Sansui AU-717 that was sent to me for restoration by @tee-jaythestereo-bargainph2120. This was a very fun restoration, as the AU-717 was a treat to work on. Being a mostly modular design, all boards were very easy to remove and work on, enabling me to achieve a fine level of detail when reworking the amplifier. No stone was left unturned; everything from inte...
Kenwood L-07CII Preamplifier Restoration
Просмотров 16 тыс.Год назад
Being the matching preamp to the L-07MII’s I recently restored, this L-07CII preamp received the same restoration treatment. Everything from input to output was overhauled, with no stones left unturned. I’m happy to have this video as a bookend for the L-07MII video as it completes the set. Sorry for the extremely long-format video… I tried to condense what was done down to a video that would b...
Sony TA-5650 VFET Amplifier Service and Restoration
Просмотров 30 тыс.Год назад
Being the first VFET amplifier I’ve worked on, this Sony had a few issues that needed to be fixed. Added to the restoration that was also needed, it ended up being a very comprehensive task. VFET amplifiers are a rare breed, and require specialized care to get working properly. This Sony was no different. There are many modifications and service bulletins that were done to guarantee the stabili...

      For a hobbyist, it is a bit overpriced yes. But if you do this type of thing for work, it’s worth every penny and more. It pays for itself.

    If you were to recommend among the HK 770, the Sanyo P55, and the Technics SE-A7 - power output aside - which do you consider the most restoration friendly and which did you like the most when all was done? Thanks!

    • @PrimeHiFi
      @PrimeHiFi Месяц назад

      Definitely the SE-A7. It’s really a wonderful sounding and performing amplifier. I still use one in my reference system to this day. The hk770 is dead simple and incredibly easy to service, but the SE-A7 is still fairly straightforward.

    Great! Love the power cable and interconnects... Wiring looms - use thread to bind, looks wonderful, zip ties are very "industrial". I get a lot of grief for soldering and not crimping, but you've proved a point here. Testing - use a reactive load (speaker coil), this makes a difference compared to straight resistive, or at least a range of resistances - 2-16ohm. These older amps are wonderful and respect to the owner. Loved watching this, well done!

    I sold audio gear in the 70's and 80's. I owned a Vfet amp and have to say they were some of the sweetest most open sounding amps that ever came around. I worked for a dealer that sold Ohm speakers and in the mid to late 70's was their west region sales rep. Those Sony VFet amps sure were sweet. It was so satisfying to watch your restoration.

    Hi, I have a 725 hooked up to a 770; when i turn ON the 770, the red power light comes on, but none of the indicator LED's do not turn on. I purchased brand new RCA's just to be sure, but still no dice. I bought the pair from an ebay seller and he swears up and down that it "was working".... Any advice would be greatly appreciated

    I am having a headache watching your video as you move around quickly while holding each circuit board to show the components that possibly needs replacing. It would be better if you keep the circuit boards on the table then slowly move the camera along the components including the opposite soldered board side as you explain the possible faulty parts and your suggested solutions to restore vintage stereo. Your video presentation is very informative and Love learning from your presentation.

    Hi, I’ve just come across your youtube on the Sansui AU717 amplifier restoration. I live in the UK. I take it the AU710 is the same as the AU717 due to it looks identical or was the AU717 made for the American market. Are the components available to buy online. I haven’t switched it on for years, but when i did, it sounds great. I am worried now if i switch it on i might do damage to my speakers or the amplifier.
