My attempt to add a spark gap to a tesla coil. I've tuned the relay(spark gap) / LC tank and topload capacitance to get a a resonant output from the primary circuit and a fairly high voltage resonance from the topload/secondary circuit.
Feel free to correct me or improve on the design. I'm specifically studying the harmonic nature of both primary and secondary LC circuits via a spark gap delivery method.
The power source is a simulated NST 8000v @50hz
The spark gap is simulated by peak cycle firing a relay momentarily.
