Lower left: 5KV power supply, Inside case: 3-amp variac, 5kv neon transformer (open core, monopolar), safety gap, voltmeter Top: extending from the insulator is 30kv rectifier diode. Upper left with red coils and mica caps is the brute-force line filter. Center: high-voltage capacitor bank. Barely visible to right: spark gap (from automobile distributor points). Right: 3rd-generation Tesla coil, oil-immersed in "Minihex" aquarium Attached at right is jack panel for connection to primary and secondary windings. Shown in spark mode. In electronic mode, plug in the pulse generator driver shown below.

The gen-3 coil is based on Tesla's oil-coil demonstrated in London in 1897. Tesla's 1897 London coil

Pots control frequency and pulse width. Trimmers extend the frequency range in this elaboration of the basic pulse generator.
