Thanks Thermionic; This is really helpfull. Does the biasing scheme used, either Grid/cathode or grid leak have any appreciable sonic signature as you describe for triodes on a pentode PP amp? Any way you prefer to design a fixed bias circuit for triode PP amps? I ask because by observing your method then comparing it to another method I see more into the topic. It may seem redundant but it really brings home the message. I have schematics for the three biasing scheme's, are they pretty much universal in their application?
