A high-voltage current-limiting transformer (T1) supplies power to the basic LC tuned circuit. As C1 charges to near the transformer`s maximum output voltage, the spark gap`s air space breaks down, completing the circuit between the inductor and capacitor, L1 and C1. The tremendous inductive kick in the circuit is caused by the inductive field col
