Re: Circlotron and class A

Hi Tre'

I thought we had this discussion. FWIW Fisher made an amplifier back in the 50s that was class A2, like our stuff is. We can drive our tubes into cutoff, but at that amplitude the amplfier is clipping.

Now, some say that A2 is not 'true' class A, that's OK- its America. But A1 and A2 are designated that way by the engineering community for a reason...
