I have a Ceriatone built DC30. I've had it for awhile and it's recently started cutting out at high volume (as if you were cutting out flipping a pickup selector switch). It cuts out exactly on the strum but not on the sustain or even feedback. I've wiggled the speaker wires, changed tubes, etc. If you back off the gain to clean, it doesn't cut out unless it's real bass heavy. If you engage the master volume and turn the gain up but the volume down, it's fine. It works the same on all four inputs, whether 2 or 4 output tubes are used. The longer it's on, the worse it gets.

Any help would be appreciated. Trying to avoid the cost of an amp tech.
