Dear Geo,
By the way, it sounds like paradise there!

Dear Geo,
That's what you get when a layman, whose mind is unfettered with
relevant knowledge, comes up with an idea! Thanks.

Hi Cliff, boy you sure opened an interesting topic! I'm struggling to

up and am learning a lot, but slowly.
The rotary switch and a hand full of Zeners, yes that would work, as long
as
it's a make-before-break switch, and everything is in synch.
But I'll stick to the TL431 and a switch to select different programming
resistor sets. Did you see that post about the primary side regulator and
the one about the bench HV supply with a CDV transformer?
Beautiful day here today, the yard was rife with turkeys, deer, even a
rouge
groundhog.

Dear Geo,
How about a rotary selector switch with different combinations of
zeners to select voltage on the fly? Old style would be a rotary
rheostat, but that would waste energy or not be practical at these
voltages and space considerations.

not a problem P. Just curious.

Well, 1 ma min isn't going to do me any good with 1kV or 2kV bias
supplies..
Back to the ol' op-amp + 1G resistor.

Sorry I don't remember the part numbers. I saw an announcement by
Microchip
a while ago, but I can't find it, must have been vapor.
TI has a TL783 ( 125V) but its a series and not a shunt regulator. Sorry
