Yea, that sim. from Bolt was a replica of the waveform Romero posted; I wished he could find those files and you can do a sim. on it. I came close but can't tune it with just the AC caps alone. I can't change the coil resistance on the super glued coils easily. I like the idea of mariuscivic(?) on the OU forum where he proposed to use CD's sandwiched with magnets and coils where he can move things around easier and much cheaper than using more solid plastics just to prove/disaprove concepts.

Using the bias magnets will tune the coil values. So, you can play with both, coil values and capacitor values. These bias magnets have another function besides tuning the coil value. I showed that at OU, first page of the 3D simulation thread. So, my advise: tune the bias magnets first for that purpose. Don't forget to do that with a fixed load and keep that load while tuning. Another thing you might check is the resonance timing towards TDC. During resonance the coil impedance is equal to the coil resistance, so it obtains its lowest impedance value at that point in time. This is the moment where the energy of the coil + parallel capacitor is easiest to be transfered to the buffer capacitor. An emptied coil capacitor allows for maximum BEMF current in the coil, charging that emptied capacitor. Maximum BEMF current flow in the coil at the wrong moment in time will cause unwanted drag.
