Re: Hello Listers
Your sec coil diameter is too small and will give poor performance. Would
suggest 4-6 inch dia sec coil with height/dia ratio of 4.5:1. Wind with
#26 AWG wire. If you send a large SASE to me I will forward you a design
on paper that will work. It features a 4 inch dia. sec coil and 17-20 inch
output sparks powered by NST (neon sign xmfr). Send to: Resonance
