Hi Peterae
Another trick I learned in building these oscillators is to add some resistance in series with the 10nf back to the gate so that when you hit the TVS diode conduction point you don't hog too much current out of the circuit.
This is important for blocking oscillators where high efficiency is required, if you don't care how much energy you burn in the "tickler" circuit then no problem.
As you may have seen in some of the circuits I have posted, I sometimes use a potentiometer divider to precisely adjust the feedback into the gate, rather than slamming it hard.
For a Don Smith circuit, this may not be an issue.
I have always liked playing with LC series circuits, and yes, the current can go to infinity in the ideal world.
Good luck
