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.
