Original poster: "D.C. Cox" <resonance@xxxxxxxxxx>No, it just becomes another parallel load. Really has no effect on HF currents trying to enter the xmfr.
1,000 Ohms 50 Watt resistor in series with each bushing as per the Terry filter is the most effective method of preventing NST damage. We also use a 40 uH RF choke just prior to the sparkgap with caution --- It must be remote mounted --- can not be under the coil or it will pickup induced currents from the pri coil. We use a remote box for the power supplies on most of our coils to prevent this problem.
