Hi Dmitry,

Im currently at 2m sparks (80 inches) using a 8x36 inch coil.  My 
topload is a 6x24 inch toroid which I think is too small for my power 
level (2KW with SRSG).  I get lot of strikes to the strike rail (4 
inches above the primary) and if I raise the toroid some, I get 
corona and arcs from the corona ring to strike rail.  I will try to 
lower the strike rail an inch or two, and I'm currently making a 8x32 
toroid that I hope can be raised further and still have it shield the 
corona ring.  If I can get the breakout to start further away from 
the center axis of the coil, I hope strikes to the strike rail will 
be less frequent.  Anyway, hope this gives you an idea.  You can view 
the coil in its earier configuation (last year running at an 
estimated 500watts wall power using two 15/30 NSTs with a static gap, 
computer simulations show a PF of about 0.5)  The coil part and top 
load are the same as I have today.
