Old SS amps


What are people's experiences with old SS amps. And I'm talking old like close to 20 years. I guess this can be called vintage(though to me it's yesterday.)

 

Either you bought it new and have had it that long or you bought it used.

Is buying it used a really bad idea even though it was owned by one person with no service issues? Like an old Pass.

I hear something about capacitators needing to be replaced. Should it be avoided like the plague? Am very interested in one but don't want to be stuck with a cat in a sack.

Thanks for any thoughts.

I have quite a few vintage or old amps that I use every day. In my living room system I have a Thredhold S200 class A amp running through an Audio Resesrch SP1 preamp into Wilson Watt/ Puppies.

    The Threshold I got was a one owner who had it serviced before I bought it, new caps,etc.. It works and sound very nice. I also have a Krell KSA 150 which I bought after it was serviced by the previous owner. It’s my main amp in my dedicated system and I will never part with it. 
  Some older gear is just as nice sounding as newer stuff, maybe not as low a noise floor and the cosmetics might not be up to snuff for the wife but I wholeheartedly believe you can get some excellent equipment at good prices that will last another 20 years.

   Then at that age they probably would be collector items and fetch a good price on the market. Don’t be afraid to take the plunge and buy vintage gear if it’s been properly maintained. I haven’t regretted one purchase yet and I have a ton of vintage gear.

Was listening to a couple of days ago with a friend's Dynaco ST-70 which he had it recapped a few years back. He claimed that he spent some $$ to put in premium parts. Well that really paid off. Driving some JBL speakers, they really sound great. but he claimed that before the re-cap, the music was really unlistenable. Those ST70 he got were from the 70's and was never recap till recently.

 

Tinned Compressed Air with a Straw Nozzle and Deoxit is a real friend when entering the inner sanctity of the Vintage Circuits, Panel Control Dials and connections scream their thank you when getting Deoxit Treated from the Devices innards. 

Many Many sing once more with a few minutes of this care being administered.  

I bought a gently used B&K ST-202 power amp in the early '90s. That thing worked perfectly from day-1 to now. Sounds pretty good, too.

 I have 3 power amps, 2 vintage and a newer one. I like my old Phase Linear 400 Series 2 amp. Sounds as good as anything newer IMO. Could do with larger power supply caps and and more reliable output transistors. But for that investment it would well worth it. 400 watt amplifiers are insanely expensive now.
