If itīs the same amp weīre talking about: Fender 15watts - class A;w/12" speaker Man, thatīs a lot of power! Those class A 15 watts equals at least 40 or 50 "normal" tube watts, A modern transistor amp could easily be a 100 watts, and still not be able play up to your class A 15 watts. class A is the cream of tube amp circuitry everything else could sound ok, but still would be a little second-rate... That fender is the best thing that happened in years! Bjarne R PS. Sorry about shouting, I canīt find the "unbold" button....:-) Ds.
