RE: Amp running hot

Posted by FenderLover on November 29, 2010 at 22:36:54:

Maybe check the PS circuit for shorts or bad caps. Bad solder points. Etc. When you modified the power tube circuit, what voltage did you drop the plates to? How hot are the 6B4G running?

Have you changed any IC's or any internal components since the last time the unit ran ok? Is it possible that an instability has been introduced into the amp?
