You can also look at the LCL configuration as a bandpass filter where the load is in parallel with the capacitor.

This is difficult stuff!

Do we use the parasitic capacitance (self resonance) of the coils?

I have not a clue where to tune the pulse generator on.
High peak(s) of the bandpass, there are more peaks (three) in the Bode diagram.

Where can I read "Frequency Bypass Coils"?

Thanks!

Yea I think you use the parasitic capacitance of the coils.
Stan's refers to the L1 choke as a "Frequency Bypass Coil" in this document which you can download from my website http://www.globalkast.com/docs/Stan%20Meyer%20Schematics.zip

Here's an image from the document. Notice what he has written by the L1 coil.

Where are we supposed to get the 'resistive wire' from?
Is this more evidence that Stan did in fact use SS 304 wire in the vics and not copper as artinvegas hinted at before?
Cheers

Tony,
Ok he called the coil "voltage frequency bypass coil" used to meet a desired voltage amplitude during gas production.
Could mean anything. 8)

Did you measured the parasitic capacitance of all the coils, unconnected on air core and/or ferrite core?
If we make use of this self capacitance we can increase this by more wire coating insulation.
as capacitance appears between the wire and insulation, what Stan also explained in the brief.

Do you still believe in your AM theory?
Wondering how it behaves when I test my real setup connected to a wfc.

Nice pic Tony! Pretty much says it all, doesn't it? Same coils, different names...

Yes! If you pulse the circuit just above the resonant frequency, you should get an AM waveform.
