RE: toroid for my coil.

Hi Luke,

My big coil (15/60 NST, LTR, sync gap) now has a 8 x 32 toroid on it and I 
"still" think it is too small!  The arcs hit the ceiling and floor, but it 
still gets four streamers most of the time until one starts to really 
dominate and reach out.

In my humble opinion, may it as big as you reasonably can.

I think the toroid an my small coil is too small too...

Cheers,

         Terry
