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