Hi Matt

Some x-ray power supplies don't use high voltage caps. High voltage DC
filter caps are used when it is necessary to supply the x-ray tube with very
precise wave forms for precision imaging. In units which employ small high
frequency transformers, high voltage caps are used to triple the voltage. In
these cases, the caps are located inside the transformer tank. The
transformer you found will have DC output, but with some work, it can be
modified to AC output. If you get the transformer, feel free to e-mail me on
how to make the modification to AC output. The transformer is most likely
good. X-ray transformers are works of engineering art. For the most part,
the DC filter caps use mylar and are unsuitable for tesla coil application.
For us the unfortunate aspect of x-ray transformer is that the high voltage
ports are recessed, requiring the use of x-ray cables. If you see x-ray
cables with the machine, grab them. A pair of new x-ray cables can cost
$600.
