Hello,

I wonder what is happen from a biasing point of view if one triode , say 12ax7, is cathode biased through fixed resistor say 2,2 k, for a certain potential point, say 1.6 V, but I put in the grid a large 10M resistor as grid leak, to serve as convenient load for previous stage ? As know such of big grid resistor create by "leaking" current a voltage potential I wonder if the initial bias fitted by cathode resistor will change, please? Thanks

Or...if is changed it will be disturbed by operational input voltage condition swing ?
