[Amps] Tuned input design / measurement questions

[Peter Voelpel]

The RF cathode current is anode RF current + grid RF current.
The return path imho for it is through the input impedance and chassis
ground, not through the transceiver.

If you don't have a tuned input circuit in the amplifier, then the return
path for the RF cathode current is through the coax and the transceiver
output tank. This causes the performance to be dependent on the cable
length. It also might damage components in the transceiver.
