Hi Murf, it might be either a tube cathode that is getting phlaky or bad tube pin connection. I would look at the 6K7 first, wiggle the tubes a little, poke around with a wood stick then measure voltages when it happens. Also the grid caps should be looked at. When the change is distinct like this the cause should show itself.

Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
