The control system of the Tesla coil is built of PWM TL494, then goes to the operational amplifiers TC4420 and TC4429, and then to pulse transformer. Input signal keys transistors. Resonance frequency is approximately 1MHz. The primary winding consists of 9 turns by a 4mm2 LY string. The secondary winding is 1500 turns by 0,18mm wire.

The coil is powered from 40V, at higher voltage the wire melts.
