1) Be sure to ground the neon sign transformer case.
2) Before you can decide the capacitor size you need to know the current of
the neon sign transformer (NST). Also, the cap is matched to the size of
your sec coil, length of wire on the coil, and the size and type of HV
terminal you use. For example, with a 7 kV xmfr delivering 60 ma into a 4-6
inch dia sec coil with a height/dia ratio of 4.5:1 and a secondary terminal
of around 12 x 3 inch toroid, a good cap match would be .01 MFD. All these
variables must be considered when matching the cap to the system.
3) A 4 or 6 inch dia sec coil with a height/dia ratio of 4.5:1 will work
good.
