Sansui AU-717


Bought my AU-717 integrated amp new in 1977. Have used it intermittently over the years and it works and sounds great, 45 years later.  The cover has never been off and I still have the owners manual.  Any reason to have it serviced?  Caps, etc?  If so, why?  And can you recommend a knowledgeable service resource in the Atlanta area?  
 

I generally live by the “if it ain’t broke, don’t fix it” philosophy but suspect that may not apply here.

I would honestly go to DIYAudio or Audiokarma and reach out to the folks there for some thoughts on where to send it.

 

Understand the reluctance to ship, and you may get lucky and find someone near by. But, better to ship to someone who will do it right? Again, the person you are looking for, could live within driving distance and may be a retired tech who is working out of their basement - someone only be found through community circles.

Secret handshake is a must…

@chocaholic Any technician competent enough to service a Japanese receiver can do the work just fine. Just have him put in Nichicon or similar quality capacitors and you'll be fine. Bonus tip: ask him to use SN63 solder if he does not already.

SN63 is a 'eutectic' solder which means its almost impossible to get a bad solderjoint with it since it goes from liquid to solid so quickly.

The unit is very easy to dismantle and work on .

Discharging the Caps is where you need to be careful.

Schematics  are available on line-Tech needs an Oscilloscope -Some soldering skill and a Variac  wouldn't hurt.
