This would be a lot easier to find out if it works if the issue weren't so fleeting, as in sometimes days between. Because as has been said maybe the issue doesn't happen because this mitigated it, or maybe just because of the random unknown nature of the failure.

I thought it had yet to be proven that the audio fault always corresponded to the oscillation seen on the scope.
I think that assumption may be preventing or at least slowing down solving the problem.Originally posted by EnzoI have a sign in my shop that says, "Never think up reasons not to check something."

At first I thought it was always following the oscillation, but I have since stated that a few times I have seen it do the opposite. The latest failure mode did indeed have a collapsed wave, but I have seen the opposite.It's weird, because it WAS working fine.....

I have jiggled and jostled and pounded, it's not mechanical. Touching several HT places makes it reset, not just tube pins. As mentioned even probing B+ feed to OT makes it reset.It's weird, because it WAS working fine.....

I guess no difference with footswitch connected or not?

Footswitch is not in play. Reverb is disconnected, and tremolo tube is out, because one tridode was shorted when it came in, so I pulled it. Customer has a replacement at home he wants to use.
I have buttoned this back up, I have other work I need to get to, and I have spent over a week with this on my bench. I fixed the complaints it came in with a long time ago. It only does this issue about once in 10 - 15 times of powering up cold, and is corrected by flipping the power switch a time or two. The customer only plays at home, so I guess in this case it is what it is. This is a very weird issue that I must accept I don't know how to solve, and move on.It's weird, because it WAS working fine.....
