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.
