Tony,
I have scanned a copy of a GE booklet on testing power tubes up to the
4-250A. It doesn't mention any of the 4CX-nnn types (because GE must not have
made any of them). But the setups would work. I don't have anything on the
4CX-600 but do have the 8-page spec bulletin on the RCA 8122. If you want
copies, let me know.
I agree with Steve that the TV-7 et al are too light weight to be useful in
doing valid testing on these tubes.
