High Powered High Voltage Pancake System: "The Tesla Coil Of The Future" - Early Testing Phase 3600V - 7200V Potential Transformer [Originally a "small" 14.4kV / 480V Pole Transformer, powered with 110V] .02 MFD Sangamo Mica Transmitting Capacitor 5-series 1/2" Tungsten Self-Cooled Spark Gap 6-Layer Reactance Coil Pancake Coils: 8" Diameter Primaries: 3.5 turns of 1/2" wide copper strap Secondaries: 175 turns of 31 AWG magnet wire Insulation: 50% Beeswax 50% Rosin Input power: 100 - 1500W @ 110V |
 High Power Discharge - Flaming Arc, White Color |
 Medium power: Note the peculiar "hot spots" on the discharges. Spark Gap is opened too far, and discharge begins to change from flaming arc to a very hot brush discharge. |
