I wonder if you could enlighten me about your Xformers. I have a 30mA
12Kv neon and the wattage on the nameplate says 360W. Do these
tranformers really draw almost double the nameplate rating?
Also I have been running a TC with 2 30Ma 15Kv Neons and I only get 30"
sparks and I am sure they do not draw 2.5 Kw!(they would have blown my 8
amp fuse) Are these modified neons you are using? If not, please tell me
the secret of how do you get such long spark lengths from such low

Also, what is a potential xformer?

Cheers and some confusion from down under,
