Can you monitor B+ voltages as the problem occurs?
Do the heaters of any of the tubes dim or go out when the problem occurs?
Again, some simple observations can narrow down the likely causes.

the audio goes dead as well. I didnt notice, but i wasnt looking, to see if any of the tubes dimmed. How do i check the B+ ?
