You might be able to find a transformer from a linear power supply for a
HeNe laser. I use one probably rated 20 watts with an output of several kV.
It was made by Inglot Electronics and ripped from a Uniphase lab laser.

Old HeNe lasers in the rectangular metal boxes tend to be made like this,
before encapsulated switching power supplies became the standard.
