1. The main secondary of the transformer must have an inductance that is equal to or less than the inductance of the total inductance of the chokes as defined in 2a) and 2d). Otherwise resonance will be impaired.

2. a) If the chokes are separate from the transformer core, then the calculated resonant frequency must be calculated using the total inductance of both chokes together.

b) If the chokes are wound on a transformer core but separate from the step up transformer, then the calculated resonant frequency must be calculated with 2X the total inductance of both chokes together. In my simulation, both chokes were of equal value.

c) I am unable to simulate a transformer with multiple secondaries but by theory assume that if the chokes are wound on the same core as the step up transformer that b) still applies.

d) In the case of b) and c), the secondary maximum inductance can still be calculated as if it were applied to a).

I have proven all the above in simulations exactly as Meyer's schematic shows, but without the blocking diode. I have a source voltage of 14V and I get charges on 20nF cap at 4kV at resonance. I haven't figured out how the diode fits in yet as when I put it in the circuit the max charge on the cap drops to 110V.
