Hi all,

I'm a bit unclear as to the measurement of Gm.

Am I correct in assuming that

a) the level of audio-signal injected into the grid circuit is fairly critical and should be a stable 100mV rms?

b) the audio frequency is not that critical. What is the nominal frequency of the Sussex phase-shift oscillator?

Next question, how does the gas test work?

Thanks guys.
