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.
