Are these tubes new pretty much? If they are its probably just a bad one but i think you said it follows no matter which socket you put it in right? If not check the neg bias voltage at pin 5.You should be able to vary it from neg 27 to neg 50v as I recall on this amp.A leaky coupling can cause your problem to but its probably the tube.
