Well, I just happen to have a 2kv, 10ma. transformer - open frame,
coated in black tarry stuff, now hard & brittle. It works fine, and I'd
been wondering about it as a little TC tranny. It was originally for
the EHT in an old (40s/50s) CRO, I believe. I have various caps that
would probably cope with the voltage, too.
Do you think it might power nicely something maybe 1-2" dia & say 6"
tall ? Have you ever made/had/seen a TC running at those specs ? Spark
gap types ?
Thanx for any comments,

'Down here', in Australia, anything other than 30ma neon transformers
seem pretty rare. A few shops have told me I'm unlikely to find
anything else, and 1 or 2 others that 60s were used 'ages ago' and any
you find will be really old. Bummer ! I currently have two of them
(30ma) at 15kv in parallel, and it's OK so far.
