I don't have my data here with me, but as I recall, the 4cxnnn
tetrodes are NOT good candidates for using as triodes. They become a
low-mu triode with a very fragile grid. If you want to drive the
cathode, and ground the control grid, you should still plan on
running the screen grid at its normal potential w/r the cathode, i.e.
NOT zero.
