Re: Primary-secondary spacing

Paul:

I used 2 1/2" primary/secondary radial clearance, on one coil with a 15"
secondary and had very good success.  Just keep the coupling light while
doing the initial shake down testing and you should have good luck.  Shots
of this coil are shown at www.execpc-dot-com/~ccurran
