Re: HV power source.

Has anyone ever tried to use ignition coils (possibly several?) as an HV
source for TC use? If not then does anyone have any ideas how this may
may not work? It seems like it should if one were to take the coil out
it's can and immerse it in oil. Thanks for any help.
I have used a single "high-energy" 12 volt coil, driven by a transistor
interruptor and using an 0.0047 ufd ceramic capacitor. With a secondary
3" in diameter and about 15" long (fr = about 350 kHz with very small
toroid on it). Can get about 4" sparks from a needle point to the
toroid, and a very nice "crown of small sparks" in the dark. Power
input to the coil is about 20 watts. Same coil fed from a 9 kV, 60 ma
neon gives 24" discharges.
