[Amps] Super Cathode Driven Tetrodes

[Fuqua, William]

Ok,

    Now that this discussion has gone on for some time, and everyone has had a opportunity to read various articles, here is the question.

Can anyone give me a reason why a cathode driven tetrode with the control grid connected directly to

the cathode be unstable. The screen grid is connected directly to ground. Lot mu grounded grid configuration.
