So restoration is complete but I am seeing one strange thing going on.

I can fire the unit up and have it set to a known freq. When the audio comes up it seems fine but then about 2 minutes later I get a POP and then it all comes up louder.

I know I have at least one weak tube.

What would make the POP and everything come up louder at the same time?

Once it's warmed up it's fine.

THoughts?
