Well supposedly when resonance is reached in the cavity according to Meyer there is a kind effect on the current flow… the question is what resonance he was talking about? In that patent he talked about matching the wavelength of the movement of the ions or something very close to that…
If the resonance is in the audio range than it may not be so hard to get it ringing…
If we look at the flat vic core, matching the wavelenght makes more sense. The flat core VIC has aprox 750m of wire. Assuming he used quarterwave length, the fundamental freq has a 750mx4 = 3000m. 3000m is the wavelength of a 100khz signal assuming an air core. With a ferrite in the middle the inductance increases and the fundamental will lower a little bit.
Seems more plausible. I had the flat vic transformer with the identical core and windings but no sucess in achieving resonance. The only difference is that I didnt have 10 cells in series, apart from the fact that Stan probably wire the 10 VIC transformers in series to drive the 10 series tubes.
If he had 10 vic transformers in series, 100khz fundamental would drop to 10khz just like he said in his patents and yes, the transformers works in series and it is a very common stuff in some high voltage circuits like co2 laser cutter power supplies.
