Re: using an SS White x-ray transformer

    I would just dunk it in mineral oil and let the air seep out on it's
own. Also I think you would be better off changing how the transformer is
wired by putting the winding in parallel. Giving you 45Kv at 14mA. To
current limit this transformer wont take to much either. I not sure how well
it would mork on a tesla coil however. The voltage is rather high and the
current is rather low.
