|johan||Class A to AB ?|
just a little question..
I know about the problems assosiated with biasing a class AB amp into class A, but what about going the other way?
I have a little Gibson-GA40-knockoff and I am thinking of increaseing the cathodersistor a little to make it pass over into Class-AB territory( or at least sniffing the border..) for no other reason than convenience when replacing the tubes on the road and far away from my oscilloscope
is there anything I should be aware of, other than crossoverdistortion and possibly a few more watts on that old speaker and output tranformer?
thankfull for any answer..
