These transistors are probably the perfect solution - if yours are really blown! Turned out mine weren't. Swapping them in didn't change my problem. Turned out some numbskull had been into the amp before me and resoldered a wire to the wrong place. Found it after much time and expense. If it looks like someone has been into the amp before you (very likely scenario), check EVERYTHING before starting in to swapping parts! Literally, one incorrectly soldered connection ... Vintage Vibe came through with flying colors.
