In Reply to: RE: In Pentode, G2 is of prime importance posted by drlowmu on August 9, 2012 at 07:29:19:
I know nothing about pentode amplifiers, but as I understand it G2 needs to be held firm at a certain constant DC voltage in relation to the grid, etc. Thus I can see why some of the alternative schemes you pose above would potentially be at least a little flawed. But since the G2 supply is not subject to signal voltage, i.e., it does not have to "recover" from anything, as far as I can tell, why is it so important that the G2 supply be "low DCR"? It would seem that any decent low noise and stiff supply would be sufficient.
