Re: Paul Millott's Coil
Hi Paul,
A few comments:

Can you find out/measure it so I know for sure? Before anyone jumps
in and says that this voltage is too low for anything, I have a coil
here putting out 4+ footers on dry days with the gap set to 5 - 6kV.

I've only read the ad for it. System output is typically dictated by
input power if tuning/coupling is OK. Optimum terminal size for the
power you are running at will assist greatly in getting long
discharges.
> I also noted that as you close the spark gap the arcs get shorter.
Closing the gap reduces primary cap voltage (and energy) before the
gap fires.

Another plea. Would you please mail me offlist with FULL details of
every component of the system - enough for me to duplicate it EXACTLY.
This should avoid my having to build another system. If I can't
identify the problem from this, I will build you one.
Thanks,
Malcolm
