Old SS amps

Been using a Sony 3200f since new in the early seventy's.  It was a party amp and quiet listening amp.  Always and the only problem is a burned out "on" lamp.  .  Took it to a McIntosh test and was told by Mac tech it was a "good little amp."  Never serviced but the "on" lamp burned out about 30 years ago.  Now it shares duty with a Decware for fun.  The differences are there but not huge.   A good find would be a bargain.  Good ventilation is essential.

As with so many things in life, I believe the answer is "It depends.". I would say that looking for something from a company with a good reputation for quality and, even better, one that still services their gear, might be optimal but I wouldn't let it scare me off if they don't.

The key is finding a good, reputable shop. If you're looking at Pass, then the answer is likely just send it to them. If you're looking at other gear, then finding a good shop is paramount. 

I had the luxury of visiting the shop I'll be using out of Austin. I feel very good about working with them. 

Happy listening.

I have a vintage 1982ish Adcom GFA-2 that I bought used in the early 90s. It was my first hi-fi component that I owned that wasn't a hand-me-down from my father. It's slated to be recapped. As is, the GFA-2 is a fun amp to use but it's not the daily driver. I only keep it for sentimental reasons, but I imagine, once recapped I could sell it for more than what I paid for it. I think I paid $150 for it at the time. So I'd say I got more than my money's worth for 30+ years of service. 

Id plan on having amp recapped at some point if you buy it. Ive read that electrolitic capacitors dry up, leak, swell after about 15 to 20 years. Probably factors such as cap quality, use, environment play a part.

Bought a Carver M400 amp and C4000 pre  new in 1980.

Waited a bit too long, but had them recapped 40 years later. They were in storage about 10 years of that time.  Definately needed it.

That’s mostly an urban legend though. Look at your Carver M400: these amps are notably unreliable due to their tight packaging and, well, Carver - yet the caps in it have lasted 40 years.
