RE: Magnifier Driver coil design

Hi Steve

Your DRSSTC magnifier stuff looks great! I like that bit of math you did
that suggests you want a much higher inductance secondary coil than folk
normally use (none of that hookup wire business)

The magnifier with primary current feedback can end up at any of three
possible resonant frequencies. One of them (afaik) will be at a frequency
close to the secondary's own resonance and develop most of its voltage
across the secondary coil. Do you know which of the three you're operating
at? I guess tuning the primary low is helping to persuade it onto the lowest
frequency (which I reckon is the best one)
