I presently have 5 microwave transformers which I got when I was at Uni
(from the halls of residence - the half-life of student microwaves is
short!). There was a back issue of TCBA news which had a good guide to
wiring the things up. I can check if you want. Whilst I haven't had the
opportunity to try it yet, I would be inclined to pair these up to get
4kV at 250mA. I guess a welder would do for current limiting. (any more
than this and you would have to look for new places to plug the things
in!).
I once phoned up a local plumber, who GAVE me three oil furnace
transformers. These are the poor man's neons, and served me pretty well
on
my first coil. Hamfests are also a good source of hefty transformers.
Whatever you do, don't buy anything new! My last 10kV 17mA unit cost
10p!
Hope this helps.
