I need a 10-15KV supply for an electronic air filter.
Thought I'd pick up a free CRT TV and take the anode supply
out.
What's a typical relationship between CRT size and anode voltage?

Alternative sources for free HV supplies at near zero current would
also be helpful. I was surprised I found nothing on ebay.

How about using an oil burner transformer? IIRC they're about 10KV or
so...

23 mA is a *lot* of current for this application.
A dangerous lot of current.
