[Amps] tetrode reverse screen grid current

[John Lyles]

I'm think you could work out an automatic circuit that sensed when to 
load the supply, when current is coming back into it. That is 
essentially a shunt regulator of sorts. Just more complexity than a 
fixed Resistor. Living with reverse current at certain power levels is 
like living with a mother-in-law.....
