Just wondering if it is necessary to take in an amp that was purchased used and is several years old to get it bench tested to make sure it's operating optimally. Any need to do that?

Can you give us more info? By 'several' years old, I'm assuming it's under 5 years old? Tube or SS? You should also ask the owner when it was last used and if the unit was stored in a 'proper' location.
By doing a visual inspection, you should get the idea of how well the owner treated the amp. If it looks good, try it out. I doubt you'll need to take it to a techie.

OK. It's an Odyssey (ODL) Stratos SS amp about 5 years old. Seems like it was treated well and sounds great. But my question was not necessarily geared toward my particular amp, but, in general, is there a need to get a "tune-up" of an amp every few years?
Just as with tube amps, sand amps are "biased' to specs and can drift. Fellow over at AudioKarma did an excellent post on this. Part of the jist was how overlooked this is and how easy of a DIY it is. If I can find it, I will post a link...
Otherwise unless there are upgrades to be gained by having a Mfg. certified tech give it a once over, service is not essential IMO.
You talkin bout Echowars post on measuring DC offset Bruce?

I measured my 34 year old amp and it was like 5 mV and 9 mV so there was no need to adjust. I still have to clean the pots though.
Yuppers... that's the one..
Problem is that you need to know who "tunes" it up. Chances are that most techs hook a pair of cheap bench speakers up and say "yup, it's fine, that will be $93".

I think Echo lives in my community and I was wondering if he would want to bring my SA12 back to current without changing its overall layout.Quote:

I have watched him from afar and am not sure if he is approachable for these types of efforts?

Henry,
Lots of people send him their old vintage amps for him to tune up. I dont know if he is familiar with your amp but it is worth a shot. He seems to be very helpful and knowledgeable.
Is there someone around that could give me a good reference who has dealt with him for me? I would hate to just send a blind email or pm over at AK...
Thanks Gate!

Wardsweb or Russ probably know Echo pretty well.
REALLY!!!!! My man Russ gets around don't he.
Glenn is a good guy, you should approach him with your questions.
Russ I sent you PMQuote:

Use my name or Russ' name. Echo is a great guy, but inundated with requests for service. He may take a couple days to get back to you Henry, but he will.
Yup, Russ gets around. Wonder how he found a great site like AudioKarma?
