Block diagram of my solid state harpin circuit.
Both mosfets switch high side, and use pulse transformers to do so.

new design, based on the same as before.

But without killing the resonance in L2 with a diode.
Diode will be replaced by parallel cap.
series cap will store inductive negative spike of L1 until it has reached overvoltage and internally discharges. giving a disruptive discharge.
this should occur at the  maximum voltage of the resonant sine.
. giving the increased voltage at the beginning of the pulse of coil one.
giving more voltage in the resonant L2 also creates, more magnetic field in L2. which is felt by L1 and L3

L3 is still tuned. to the process of L1 and L2, producing the output.

series cap of L2 could also be on the ground side, and ground could also be V+ for the L2 coil
