CW SSTC w. secondary bottom feedback around @ 80VDC in

During some construction problems of a new MMC for my induction heater i had an idea about using the existing IH setup for driving a random tesla secondary.
I had only to do two changes such as replacing the power current transformer with a quick and dirty wound primary coil and placing the feedback current transformer at cold end of tesla coil.
No greater problems were noticed even with the much higher frequency as in normal operation.
Due to a recently occurred MOSFET failure i had to use four IGBTs due to running out of MOSFETs.

Scope screen shows NOT high side signals but primary voltage of GDT because i don't have an insulating transformer yet.
