SS amps should and IME do run 24/7 for years. I've got a pair of
Dyna 400s that still meet spec, bought in 1975. One is 100% original
and the other had a few small parts changed. I have a 100% original
Dyna ST-120 that still meets original spec!

Of all the SS amps you would hope to fail. I think these might
be at the top of the list. To think of poor people having listened
to these for years and years fills me with pity and horror.

Frankly, on the bench it's not that bad-sounding of an amp if its in good
shape. I should put some files from it up on www.pcabx.com. I think many
people would be surprised. I think that since it was fragile, a lot of
people ended up listening to broken ones.
