REPLY:
I question whether tubes in parallel can radiate RF into each other.
There is a small amount of capacitance from plate to plate, but the
voltage at each end of the "capacitor" is the same, both in phase and
amplitude, so no current would be flowing unless the tubes are
mismatched for some reason.
Correct?
