Doesn't the magic smoke come out if there's even a tiny bit of current
leakage draining away the voltage that L1 transferred to MN1's base? Or
if the control signal to MN2 has a bit of a bounce? At least in your
slightly obfuscated circuit, that would leave MN1 pumping out about 2
times its rated wattage.

PSpice needs a "circuit board in the tropics" mode.
