Hi
I have an SSE, about 6 years old. I use the SSE for the treble end of a bi-amped system. One channel is noisy (loudly hissing, sometimes pinging) the other almost silent.
Swapped output tubes - no help
Replaced output tubes - no help (except no pinging as yet)
Replaced input tube - no help
Recapped entire board - no help
Re-made all terminal connections - no help
No matter what I've done the same channel has a problem, the other channel doesn't.
Anybody have any other ideas? Could the 10M45S be the problem?
Thanks,
Charlie

Resistors are a common noise source. Often a bad one is temperature sensitive. They used to sell circuit freeze spray at Radio Shack or electronics component distributors that catered to the repair industry. I don't know where to get it now, but I know it still exists, we have it at work.
You spray a warm component and it drops the temp about 50 degrees instantly. Obviously don't spray a hot tube or your fingers.
You spray each part one at a time. If the noise changes intensity or pitch you have found a bad part. Resistors usually quiet down when cooled, semiconductors can do anything, but should not do anything other than a small change in operating point.
