Something i forgot about is how quiet these amps are at idle . Since this is your first tube amp it might not have been all that noticable to you but these AC50 Combos are about as quiet as it get's in a tube amp, it seems to me anyway.
FWIW , i just made a phone deal on a demo amp like these and need to go pick it up. A cool guy on the internet told me about some mods he performed to his that i want to try while leaving mine stock.
I seem to buy everything in two's - whats up with that ? Sheesh
