Yeah, from what I have read, it looks like two or three boards. The
primary is just a long string of reistosrs. each about 3.5" long.
Chaddock makes resistors for 25kV and each is about 3.5 inches long
so one 50m to start will offer enough resistance to limit currrent
and still offer a reading.
It is the enclosure that will need to be considdered, but that too
should not pose a probelem with pleanty of board space between the
traces and the mounting screws.
Thanks for the help all.
