Using a soundcard to test one would have a frequency limit of about 25Khz. Also, RMS volts would be quite limited I think? The coil that I'm testing uses frequencies of 350Khz to 1.5Mhz depending of the load I have on the secondary.
These resonating circuits work well with a fixed resistive load but as soon as you change the load you need to re-tune both frequency and capacitance to get the circuit as efficient as possible again.
Thanks for the picture of Hans Coler's machine. We can see that he has put much work in achieving a geometric position of his resonating coils which I believe is another state of fine tuning. The SM TPU guys should know about this by now. I had 3 coils in series before I fried the H-Bridge DC Flip Flop circuit and it was at the point when I found that the position of each coil had an effect on each other, when I had the coils positioned to give out the max output that is when the circuit blew
Thanks for sharing
