So I got a used one which was carefully packed and shipped from Poland. The problem is that the post knob is acting weird. For example when it's at 0 it's like it's in 2 or 3 but with the rest of the eq not responding as they should. When 3 to 4 it's really low and scooped and the amp sounds as it is supposed to sound past 5 or 6... This only happens in the lead channel so I suppose it's not a power tubes related issue. I swapped the preamp tubes with no luck. When I turn the post knob it's not scratchy but do you think it might be related to dirty pots?
