It 2X larger, I have a hole blown in the side of the hookup wire and this
wire keeps getting shorter and shorter. I had to trim it once and the trim
was more than it should have been, I keep trying to patch the hole but it
seems to find a way through the patch.

So what you are telling me is that I need more ice-tea bottles? If I add
more capacitance to the tank it will preform better, would I also have to
adjust the spark gap? It also might be time for more gap, I run a 12KV 120MA
neon with a total capacitance of .006uf. Another thing is that my primary
has 1 inch spacing, would it be better preformance wise if I were to reduce
the space in the primary or does that not matter? What about going with a
smaller toroid?????
Questions qusetions, I am sorry:(
Thanks!
