Hi Malcolm
Per our previous discussions I have not blown a neon since I started
using synchronous gaps giving one firing per 1/2 cycle of the AC at
near the peak of the AC wave. After further discussions with other folks 
it appears that I am probably achieving the maximum power conversion 
which is possible. I realize that your intention is to eventually go to 
DC operation at high break rates and my comment is probably superfluous.
Right now I am trying to get higher Qs and higher transfer efficiences in 
the primary/secondary circuit to maximize the discharge size. I think we 
all look forward to your results.

Good luck
