Bill,  the Baxandal cct is great in lower voltage input applications,
but the one thing you don't want to do with HV sources is ADD voltage
stress.

 
Bax is, as the saying goes, "component rich."

It's got a special purpose transformer, the feed inductor and two
switching transistors. In theory you have to add a capacitor across the
transformer to create the resonant tank, but for the application I'm
talking about it may be difficult to wind the transformer with a low
enough parallel capacitance to get the sort of resonant frequency I'd
like to see.

That's not a lot of components.

It doesn't matter how complex your circuits are, since they will never
be built.
