Top terminal is a plastic light fitting 12" diam sphere wrapped with
aluminium foil. Winding length is 21.5" single layer spaced with fishing
line - about 900 turns from memory.  Not sure of exact wire gauge, the
whole secondary has been laquered several times.  It was designed
originally to be powered by 2 x 30 mA 10kV neon trannies, but when my
cap turned out to be twice the calculated capacitance, I found I could
get more out of it using 4 trannies in parallel and adjusting the
If you are interested, there is a pic on my friend's web page. Note it
is an old pic only using 2 x 10Kv neons. The spark output has improved
somewhat since then. http://www.OntheNet-dot-com.au/~comp_guy/page3.html
