The Baxandall class-D oscillator could do it, but it needs a pair 1.7kV

it's a much higher current part (10A) than the job needs (about 1mA).

 1kv, sitting there all alone and bashfull. Not a common occurEnce.
Is this the only power source in the vicinity? Tell us more.

It's not my project. I just got asked about what a Baxandall down-converter for a 1kV 1mA source would look like.
Because it's not my project I'm not at liberty to talk about the power source. My first thought was an intensely radio-active source pushing out a lot of high energy beta rays (electrons) or alpha rays (helium nuclei), but it isn't.
