If you are running a large coil with a sec toroid of at least 7 x 30 or
larger and a primary cap of around 0.1 MFD the 7 kV 700 ma xmfr will work
fine -- should produce sparks around 10-14 ft long with 14 AWG wire on the
sec coil. If you are running a smaller coil the 700 ma may be way to
excessive -- around 120-200 ma will work better with a pri cap size of
around .03-.05 MFD. Good luck in your work.
