Wow
Been busy with life stuff for a few days, and come back to find everyone WAY ahead..
Great work Aromaz.
@bodkins, am I right thinking the circuit will work without 2n2222, just ground to first 2n3055?
I was going to post the following.. Guess I still will.. Great way to generate signal frequencies. I'm inclined to think along lines of Aromaz now, that letting circuit self oscillate is good way forward, but having done heaps of research and gotten all the parts, I might build my little signal generator anyway - should generate compression waves only meters long. That'd make wireless receiving coils the 1/4 of wavelength tesla stipulated would give high gains in power.
This stuff just blows your mind eh..
/// Here's the schematic I'm going to use as a signal generator, except adding a 12 way switch to select different coils, uh to mh. Also, another 12 way switch to select sets of caps, 1-10p variable, 10p-80p variable, 60-160p variable, 1n, 10n, 100n, etc. Also, going to add 1m ohm pot somewhere, either side if inductor, methinks.

And here's link to pic using Tranny in colpitts oscillator that has earth input to base..

I have also been interested in your diode dilemma. In fact my very first own creation was somewhat of a modified Bedini circuit and it had over-unity. Unfortunately the complete thing went up in smoke – including beyond recognition was a vacuum triode that I harvested from an old junk radio in Bangkok. Since I looked everywhere but can not find one that looks exactly like that one. That was something with a JAN code and the old radio was a two-way radio ham’s Telefunken from late 1940’s – not working and seemed to been in a serious accident. However, this triode survived and gave me many interesting hours. Only later I discovered what JAN means and there are plenty of items with that code prefix.
