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.

If it powers up and is noise-free plus sounds fine no need to replace caps. If it has not been used in awhile use a variac to slowly bring up the AC voltage.

My Sumo Andromeda from the 80's has been in use 24/7 for months now. No problems and sounds fine! An example of leaving the original caps in place.

On the other hand my BEL 1001, GAS Son and Bryston 3B all need new power supply caps. They are unusable until this is done. 

Thanks JB…I think I’ll take your advice and leave it alone. I’d hate to mess with it unnecessarily considering its current condition.
