Tell me your findings / opinion...
Look at the pulse/gate waveform in the attachment.
Step-charging effect increases in a "LINEAR" fashion.
We can see that the pulse waveform never reach zero level. Stan said it sustains resonance.
So this can be the answer to keep the flux above zero in the core.
Most of us use MOSFETS why did Stan use TRANSISTORS?
Is there an bias in the circuit schematic?

You also should transistors instead of fets.
Use the 3055, for example.
Fets have some components build in , like diodes etc.
I have seen bouncing signals on my scope, which looked like resonance.
However, it was the fet that was demping my signal, and did that in a bouncing manner.
When i used transistors, the effect was gone.
Then i saw the real signal of the bemf. Just one nice negative spike.
Just try, i would say. Observe.
