[QUOTE="handsome, post: 46270, member: 772"] Ampdog your willingness to share your knowledge is matched only by your lucidity! I did notice the large bypass capacitor on output stage but I thought/assumed that it was a signal bypass that would lower the output impedance of the pair and by it's presence would create an(other) zero. I always believed that without the bypass capacitor the stage could not be driven into class A2 and with the bypass one could achieve AB2 and thus more power. And what of blocking? Whereby the integrated signal on the capacitor begins to bias the valve further into cutoff until, in tandem with the stored charge of the coupling capacitor (from high signal peaks), it does cutoff and then can only recover by discharging through the bias resistor effectively switching the output stage off for the recovery period? Is what i am saying correct? Or do these 'things' only apply to separate cathode resistors? [/QUOTE]
