I would not say that 1A at 28mHz in #16ga is a serious source of heat.

When DC current is pulsed through an L-C circuit, damped ringing occurs
at the resonant frequency. This is how spark transmitters produced RF.
. . Damped wave ringing is discussed in the October, 1988 *QST* and
September/October 1990 *QST* articles on intermittent VHF parasitic
oscillations.

Yes. That's pretty much what it looks like on an oscilloscope.

I comprehend that it is not the same path. An anode to grounded-grid arc
does not pass through the cathode circuitry. It passes through the meter
shunts to the negative HV return.
