How old is too old (for SS gear)?


I've personally not been too concerned about the age of used solid state amps and preamps, but recently a few pieces of gear I've purchased have either A) bit the dust or B) starting to make weird noises.

So now, I'm a bit gun-shy about buying used gear much older than a few years.

Do you have a certain age limit when considering the purchase of used gear?

Thanks.

IME. 15-20 years. Caps start to dry up. They can be replaced if you know what you are doing. Living in fly over country, it is hard to find techs which will work on "stereo" equipment. We live in a throw away society now. most buy les expensive gear which is not cost effective to fix. Those with high end equip are not numerous enough to warrant techs  for our stuff. Specialties are the thing. We ain't special. 😀

30 to 40 years....there are original Sugden class A still going strong even today....

It really depends on your expectations for sound quality. If it is not important, then they will work for decades. But there are deterioration of original sound quality as mentioned above and the advancement in sound quality / unit cost. 
 

if you are trying to put together the best system possible with a mid-fi or higher budget… over ten years is unlikely to be good… unless you get a great deal on something a little over that.
