So we've got a plate current that is g1_voltage_delta( X + delta ) the delta being anything not the perfectly linear.Swing the votlage more positive and we get the G1_v_d * delta as the portion running at a-a/4 and the load line will be somewhere between a-a/2 and a-a/4.
So when we swing V_g1 negative I think we shall expect to see something less( greater R value ) than a-a/2. I can't quickly visualize the sign convention here...
cheers,
Douglas---I seem to remember seeing something for triodes that calculated the load based on the plate resistance. So as one gets lower at maximum current it was closest to a-a/4( as it moved there from a-a/2), and for the phase with a decreasing voltage the load approached infinity as plate resistance went up( which is of course about he same thing as this decreasing grid voltage delta term I think ).
Friend, I would not hurt thee for the world...but thou art standing where I am about to shoot.
