[Amps] Super Cathode Driven Tetrodes

[Fuqua, William]

Sorry for typo error. Low mu.

There should be no reason for this configuration be any less stable that the usual high-mu triode grounded grid

amplifier, if fact should be more stable due to lower gain.

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.

I believe I already answered that days ago....poor
construction...layout....shielding.....component choices...etc.
