RE: streamer output - toroids vs. spheres

I just got my first Tesla coil running 10 minutes ago, and the 
topload I am using is a dryer ducting + aluminum tape toroid with a 
metal bowl stuck on top - half toroid, half sphere.  I don't have 
anything to compare it to yet, because I haven't tried any other 
toploads, but it does not get breakout usually.  (Though I'm pretty 
sure that it's the single static spark gap that's the problem - when 
set so it barely fires and sputters sometimes, the sputters produce 
momentary breakout).

try the best of both worlds,..multipal   spheres !!!

   42" with a 3" coil !! Wow, thats GREAT !!!
