[Harp-L] class A

[SONNYTONE@xxxxxxx]

Single ended, or one power tube, would be class A. You can also have Class A 
amps with two power tubes, our Sonny Jr one and two were both class A. Class A 
just means both power tubes are on simaltaneously all the time, class A/B 
means they oscillate on and off with each other at extremely high speed. That is 
the simplest way I think it can be put. If guys want to get into the cathode 
versus fixed bias, that's another topic.
