Re: The forever ongoing upgrade
4.5 times the sec coil diameter produces a real nice unit. We run this
length (actual sec wire winding length) with a 12 kV 60 mA xmfr and a 0.12
MFD cap, 20 kV rated, with 3 subdivided sparkgaps with a 250 CFM blower
behind them, and a 14 x 5 toroid. Output is a solid 24 inch long spark.
4.5 x sec coil dia.
