Here's a pair of 14kv 1000ma diodes:

You can also roll your own by soldering twelve, 1N4007
diodes in series.  This will give you 12kv at 1000ma
for under $1.

Hi Greg,

Perhaps this is not a problem, but I have always been concerned about 
the power dissipated in long strings of small diodes. Even a few 
volts each, times a dozen or  more diodes, times an amp can generate 
some heat. This is probably why I've seen strings of diodes on boards 
in oil for some X-ray units. What has your experience been?

Thanks,
Matt D.
