VTTC Tesla coil oscillates very weakly?
Hello, I recently tried to recreate Steve Ward's single 833a VTTC, and a gas discharge lamp on the torus glows very dimly. I used a neon sign stray-field transformer as the voltage source, which is regulated from 6300V to ~2kV with a Variac. The tube is the 833a. I set the capacitor/windings of the primary…
