Overunity Parametric Oscillator?

@nul-points . Thanks for that interesting post . A useful experiment would be to use a center tapped transformer as a starting point . Then , if that looks promising we could build a custom inductor with multiple taps .

I hesitate to post but for completeness, yesterday I actually checked the switching speed of the relay I was using - about 40Hz was the best it could do, everything above that was hit-and-miss!  So I went rummaging and found a physically much smaller relay which managed a much more respectable 250-260Hz.  With the same setup & capacitors, I was getting nothing like I posted earlier.  There is still an output but nowhere as well defined and definitely no AM.

Read the thread from the start, not the last post.

Operating the cores at saturation knee can cause parametric pumping effect.

Sir the link you posted appears to require membership to View?
Or am I doing something wrong?
Thanks
