Re: Hello Listers



to: Ken

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
Research Corp, 10700 N. La Reserve Dr., STE 20105, Tucson, AZ  85737.
