[Amps] HV resistor source

[Drax Felton]

So then what is the Radio Handbook talking about where it uses a 10ohm/20w
one between the plate choke and the +HV?

That's going to be quite a resistor, inasmuch as 4KV across a 30 ohm
resistor amounts to a half million watts of dissipation!  A 4KV pulse 50uS
wide, once per second, would dissipate 25W.

So where does one find a 30 to 50 ohm 25 watt resistor that can safely
handle 4000v?
