I'm late getting into this string.... It sounds to me as though you want the electronics to self destruct. Is that correct?
Here you are.......
1 - Amplifiers make good oscillators. No amplification, no oscillation.2 - If you provide *enough* positive (in-phase) feedback an amplifier *will* oscillate.
3 - At a feedback amplitude that is very near, but below, what it takes to cause sustained oscillation, the amplifier will ring or ping with noise.4 - Increasing the positive feedback beyond that in item 3, you can drive the amplifier as hard as you wish, up to self destruction if you pick the correct components.
You can make an amplifier oscillate with, or without the LC network. The tuned circuit just lets you set the frequency at which you want (or hope for) it to oscillate.
