Herbach and Rademan have 100 of these transformers...

"Sounds" easy...but I'm electrically challenged! (Stay tuned for some future
"dumb questions" on that)

Fr. McGahee,
Just what I was lookin' for by way of a power supply (had 6 neon 9K
60ma's...but 2 died, and I fear the rest are sure to follow) 

Question: I made four rolled poly/alum caps, approx. .017mfd each...I
parallel all four for about .0668 mfd total. This does pretty well with 4 or
5 9K 60ma neons for my little coil, and I was wonderin'...will that still be
pretty close to what I'd need with the 10K 300ma setup described above? (I
know I'll have to re-tune the primary a bit, but i have 3-4 turns either way
to play with) I'll run it thru the tesla programs I have, and see what they say.
Thanks again for lettin' us in on the good deal "mini-pigs" ;o) Can't wait
ta get my neon-murderin' little hands on those babies!

ken "closer to real coilin'" cravens

ps...how r u doin' with the idiots' guide?  (I'm lookin' forward to readin'
some "not quite so technical" but surely very educational articles)
