Jasonjay Posted December 11, 2020 Share Posted December 11, 2020 I have this amazing amp with a user friendly interface, but after warming up, about 30 min to an hour, the power turns off and on by itself. Does this sound like a tube problem, a power supply problem or what? I love this amp but I can’t depend on it! Help! Quote Link to comment Share on other sites More sharing options...
psarkissian Posted December 11, 2020 Share Posted December 11, 2020 Probably tubes. How long since the last tube swap? What brand and numbers are on the tubes? MkII version? Quote Link to comment Share on other sites More sharing options...
