So glad you are getting there. Shut down and shoot that control with a little deoxit and work it back and forth a few times. Might as well do the rest of them as well. Let it ll dry out overnight.

"Note well" N.B. keep the golden screwdriver away from the set until all the usual suspects such as out of range resistors, of course all capacitors, corroded tube sockets and pins, and switches (did I miss any?) are ruled out. Tubes do not usually go out all of a sudden, but are the next in line as suspects.
