Parasound JC-1 - How old is too old?

If anyone has re-capped their JC-1s, how old were they, and how much
did it cost? Thanks for the help.

Even if you got the first ones, they’d still be good for another 10-20 years.
They used quality caps, Japanese Nichicon Gold.

I feel that age is particularly important with Class A designs. All those components have been living in heat their whole lives.....

And they’re not Class-A but 400w A/B and run cool in normal mode, they have high bias switch on the back which gives them around 25w Class-A bias still with 400w B, then they run warmer, instead of 10w A and 400w B in normal mode and cool.

BTW great amps, I heard them many times on Wilson Alexia and nothing but the top Gryphon Antileon Evo could equal them, and the Gryphon "just" surpassed them at many $k's more.

I isolated four of the first JC-1s in John Curl and Bob Crump’s room at CES in early 2002 which would make the (first) JC-1s almost 18 years old. 

Geoffkait, they run class A to 25 watts into 8 ohms. For some reason this is a magic number for John Curl. After that they run class B. Run on full bias they still can get pretty hot. Hot enough that you would not want to keep your hand on the heat sink. At 1/2 bias they are just warm but most of us think they sound better on full bias even the bass for some reason.
Jaytor, mine are 6 years old. But as Geoffkait implies these amps are built much better than any of the older Krells. Also the circuitry and layout were done by the best in the industry. In this price range it simply does not get any better. Once these amps are proven, have run for a period of time without issue they are good to go for decades unless you throw one out the bathroom window. 

Hot enough that you would not want to keep your hand on the heat sink.

I measured them at high bias (28c ambient) at 55c, internal was the same, no problem for those excellent Japanese Nichicon Gold caps. So don’t worry OP buy them.

and get to it fast. They will not last long!
