By means of some fast talking and a $175 withdrawal from the treasury of Lord British, a 14,400-volt, 5,000-watt power-pole transformer was procured from the City of Austin's electric utility. This transformer, driving a rotary spark gap, provided excitation to the Tesla coil's primary resonant circuit. Normally used as a step-down transformer for power distribution purposes, the power-pole transformer was wired backward to step the 110- or 220-volt line voltage up to 14.4KV.
