Can someone give me a dumbed down explaination of how the Hickok's measure mutual conductance? The schematics are difficult to read.
Secondly, can anyone explain Eico's method of measuring dynamic conductance? The Eico 666 schematic is much easier to understand, but I don't quite get what is going on. I see the meter is sensing current at the plate, but how does this correspond to gm?
Thanks in advance, gurus!
