Hello Here are my SSTC, full bridge, resonance frequency- 117kHz without torus, spark length 20-25cm(10inch), capacitor-5uF/800V Rifa, antenna feedback, full bridge on FGA25N120ANTD igbt, fake safety ring is antenna :) I hope it somehow looks like Dr spark project.

My first tesla coil ever, it's a micro table-top VTTC.
Inspiration by Dr. Kilovolt. Tube used is RFT PL 500; heater switchable on the fly between 27 and 30V. Two-stage mains multiplier as the anode supply. Possible to switch between quasi constant-wave and thyristor (SCR) cathode interrupter mode. Fused mains supply (3A F) + cathode (315mA F). Primary 16 turns, feedback 10, secondary >1100 (0.09mm wire). The secondary is 10cm tall on a diameter of 5 cm. Resonant cap 2x paralleled WIMA FKP 1n5 1250V=
QCW mode dual 3.5-4cm streamers; 4.5 to ground; with a good breakout point, one 4.5cm free-to-air appears (pictured). Interrupter 6-7cm streamers both free-to-air and ground.
