Simulation allows the effect of unevenly spaced electrodes to be evaluated.  The amount by which the electrodes are offset can be changed by altering the firing times (TD) for sources V2 and V3.  Initially the first rotary firing is set to 1.50ms after the zero-crossing of the supply voltage,  and the second firing to 5.50ms.  This gives two equal sized bangs.  Initially the normal o/c transformer voltage is shown next to the tank capacitor voltage waveform.
