A bridge is going to deliver around 3000v on the low tap and 4000v on the
high tap, using a resonant choke filter. 3kV is way too much potential
for a 4cx250. A fullwave ct rectifier on the high tap, with a
resonant-choke filter should do about right.

do your diodes a favor and leave off the RC shunts. The reason why is
explained in the new Handbook.
>I have a Hammond 5 Hy 1000mA 5kV Choke 70 ohms
sounds good. I'm guessing roughly .2uF at 7kV to resonate it.

much more than what is needed with a resonant-choke filter.
