They discontinued the line, but some on eBay. B&K Precision 9185B also discontinued 0-400V 0.5A

i think sorensen used to be them or vice versa

0-300V adjustable
150mA out
Flat DC
I might be able to compromise a little on the current if I need to, definitely 100mA out at least.
Connector doesn’t really matter. SHV or MHV or insulated banana jacks or whatever.

Making one is kind of the last resort if I have to.

Could anyone recommend where to buy something suitable?

I did not find something smart either, so I homebrewed one, like here:

electronicprojectsforfun.wordpress.com/power-supplies/high-voltage-lab-power-supplies/a-250v-150ma-variable-linear-power-supply/

mine is 250V 150mA but if you find a proper transformer the design could be used for higher voltages.

Maybe that  helps
