Sag is another giveaway that you're in AB! If you were in true class A, the current drain on the power supply would be pretty constant.aclempoppi wrote:Used a Clubman-35 in the blues band for 8-9 years, just kind of made that leap of faith, that it was indeed what Matchless said it was. Talk about energy spent on heat, at the end of the night the guitar's input plug, at the amp, was almost too hot to hold on to. On another note, that amp sure had some moments of sag ! But otherwise, it was just a great amp. Art
..now consider: all the people who think they want class A would also probably demand a tube rectifier - yet without sag, there really is no need for a tube rect (looks cooler though).
..Also consider that the sweet spot in most push-pull amps occurs when you turn it up enough to take advantage of the B portion of your curve, in other words, most people like the sound of an AB load line whether they realize it or not.
I think whoever came up with the term "Class A" could have been a millionaire ad exec if s/he hadn't gone into engineering.
