Mark,
When I first got started, I built two of the cylindrical gaps as shown in the
funet files. I used 6 copper sections in each gap with a spacing of about
.030". Each gap had a total of about .150". When using neon transformers
for power in the range of .7 to 1.4 kva, I found that the system worked best
with one gap. I tried two in parallel and the two in series. When I got too
much gap, the system was not very reliable. It took almost full power to get
the gaps to fire and they would not reliabley stay fired - and as you say,
running at this point is hard on transformers and capacitors.
