M.Romasco	Re: Fender Champ Mods Paul, Ive got a few questions for you about the champ mod. First, why do you add a bypass cap to the 15K ohm cathode resistor - it's not in the 5F1 scematic that I have. Second, do I really need to get a new speaker? Whats wrong w/ the orig. Third, I have a Vibro-champ that I want to do this mod to. Would it be safe to leave the trem circuit or would I have to bias the amp differently? What is the approx. voltage of each plate that I am looking for? And finally, what kind of tonal differences will I get with different value filter caps? Matt out.
