Re: [TCML] DdRSSTC driver board with parts

[DC Cox <resonance@xxxxxxxxxxxx>]

WEe using a proprietary circuit we developed over a 2 yr. testing period.

With our 24" dia. sec coil it is producing 16 ft sparks that are white hot.
We qre running a steqady 100 amps, 220 volt doubler, so driven at 635 VDC.

Finn's circuit doesn't work properly for a few reasons I will not discuss
any more. I got blasted laqst time and I refuse to discuss it.

Yes, you can see this coil run at our next Teslathon.

And, p[lease guys, any inquiries on the DRSSTC caps or driver boards ----
OFF LIST ONLY as per re
