Half-bridge tesla coil, Full-wave rectified with 1000uF 450V electrolytic smoothing cap.
This coil was tuned from the beginning to be a CW coil, due to this reason it can run practically indefinitely in interrupted mode. The longest run so far ~20 minutes, it was as long as I could run it before getting bored and irritated, there was no noticeable heating of the bridge based on my finger based thermometer.
