spec are:
Secondary diameter 2.375" by 15" and wound 12.75" with Awg 28 caped on each
end,
Primary flat coil made from solid Awg 6 spaced 0.25" apart inner diameter is
6.5" max turns is 6.75",
Toroid length is 11..5" and 3.375 height,
Cap is 0.03uf rated at 35kvdc,
Spark Gap multi segmented set at 0.56" each for a total of 0.17",
power supply is a 7.5Kv 60ma Franceformer
protection I have 1 choke that is 1" in diameter wound 6" with awg28 with no
safety gap

Sincerely,
Nolan Moore
