If anyone wants more clarification of anything, please ask, my brain does work in strange ways sometimes  On that point, a reminder that my schematics are not ALWAYS full working schematics, and or they can be improved over time. Tuning is difficult because timing is everything, and I have been working on making it a little easier without using half-bridge drivers for the input signals. I have also taken heed of what Toni has said about using two diodes from C3 to the charge chokes, and this is what I have come up with which seems to make tuning easier. Use only one diode supplying to the 2 charge chokes. Use a diode from the drain of "A" and "C" before connecting to the TPU. This helps stop "C" from being fried in case of shorting the "A" discharge or HIGH pulse. "A" and "C" are only supplying a high pulse in the first place, the resonance is between the C1 and the coils, not through the Mosfets. Regards Mike
