Re: High voltage power resistors

You can use conductive/dissipative paint (as used on ESD protected floors)
on an insulating form.  Some flat black spray paint uses carbon black as the
pigment, and it makes a nice high resistance coating. (Don't ask how I found
out the hard way on this)  Not all paint works.. you'll have to get a can,
spray it and try it.  Not only that, but even within the same mfr and type,
it changes.

Water resistors work very nicely, and can be packaged so they don't leak,
are resonably stable, etc.  http://home.earthlink-dot-net/~jimlux/hv/rwater.htm
has details.
