RE: But it will matter..

I guess if it is moving and/or periodic then it's going to "see" the reactance of the choke.

If it's caused by musical peaks driving the tube to grid current, from say a song at 120BPM with the kick drum and bass guitar pounding on the down beat, then the period of the occurrence of the grid current might be 30Hz.

A grid choke with 7000Hy has a reactance, at 30Hz, of 1.3meg ohms and the bias of the tube will be thrown way off and for a long time.

WRT bias stability a person would be better off with a grid resistor.

BTW Dave, this is a setup just for you. Now run with it. :-)
