Re: twin coil system

Hi Bill, Brian,all,
    Thanks for the info on twin coil set-ups. I am hoping that if I build a
twin coil I might be able to use
it for shows. I  work in the entertainment business in the summer. (may
balls and garden party's,) and I am
always being asked if there is some way we could incorporate tesla coils
into the events. We already have
lasers and fireworks so it should fit in well. Don't know what it would do
to the security peoples radios. I
am hoping that a twin coil would be predicable enough to not take out half
the audience, who are mainly drunk
,and unpredictable. How have others got on with this sort of thing. I am
thinking of a small set up here not
my big coil, something like TTR's  mini model 12.

many thanks
bob golding
