First things first. Have you tried changing tubes ? If possible, use some older but still verified good tubes. If there is actual damage to the amp circuitry itself, it doesn't roast a brand new or more expensive set of "glowers".
If it isn't a bad tube, i would venture to say that a capacitor went south.... Sean
