Now for the rest of the story: use a high voltage FET 2Amp at 800V
across the choke and regulate it with a *LM431, programmable Zener.
I has a EICO Triband HF rig model 753, it's power supply uses 2
chokes, I regulate the outputs: 790 Volts to the final and 275 Volts
to the rest of the rig. Solid as a brick outhouse. The chokes take
most of the load off the FET's. So if the chokes saturate the FET's
take over. With all the mods I done to the EICO 753's regulating the
DC outputs is best.

Ha! Hotmodding an Eico 753. Sorta like putting a supercharger on a
Yugo :-). I can see how both could be fun, in a kinda subversive "it
should've never been sold in the first place, and I'm now going to
take it to the extreme!" sense!
