Firebird f-500 mod


I posted this question about a year or two ago. The consensus was that although it can be done, the gain that you would realize (< 30 watts, IIRC) wasn't worth the effort.

With decent tubes that amp will cruise along all day long at 350 or so. Yes it will do 500+ if you drive the snot out of it, but it won't sound good and you will burn through those tubes a LOT faster.
