What happens if the Resonance Kit of Rick Friedrich meets the Don Smith setup? That's what is shown in this video.
They are first experiments, so much more needed but the concept works. At the moment at very low power.
After making the movie I saw that the earth connection of signal generator was not connected to TC4420, when connecting that ground connection it didn't work anymore, so that ground connection must not be made.
Other experiments showed me that the ground connection made from output to input is very important is this circuit, thereby looping the energy as it seems in this experiments.
Please don't limit experiments to what I show, the circuit is so sensitive to all parts and connections involved.
Looking at the circuit some other idea's came up but that will be for next weekend :)
Please experiment at your own risk.
Kind regards to all.
