Re: [TCML] AC powered Ignition Coil Circuit

["Tedd Payne" <teddp2@xxxxxxxxxxx>]

For those interested in experimenting with an ignition coil, you might be
interested in these:

**  New 60 KV coil on eBay, the "Buy it Now" price is about half of what I
paid for it years ago.

**  3 to 4 inch spark (not arc) setup - I have quadracs and other parts
which I used to build a super-simple circuit producing 3 to 4 inch sparks.
I'd like to sell them all as one lot for cheap, I'll include the printed
circuit info for free.  Contact me directly if you're interested.
