Folks-
In a GG amp, suggestions on how to measure Grid current WITHOUT the typical
semi-floating B-.
Using a SMPS. Plate current and Voltage are present as 0-5 volt full scale.
1) Measure Cathode current across Rk, and subtract Cathode I from
Plate I in an op amp to derive Grid I?
2) Untie the grid from physical ground, RF ground with caps, measure
Grid I across a small resistor?
3) ?
Thanks for flexing the gray matter.
