Mysterious Resonant Circuit

[wings]

Excellent!!!  I was wondering ever since I saw this circuit if that was the case--you have something that now matches SM's first clues and the Boyce device as you mention.  Remember SM's comments on interesting things when transformers get slightly out of phase with each other?

My replication is in progress, and I have a few ideas for increasing the output power...

Hi Everyone,

OK, I got round to building and testing the circuit, however I have used a 2N3904 transistor, so this isn't a replication per-se. Also my supply is a not a semi-depleted 9V battery but it's a bench supply set at 9V. Also I have 100 ohm over output instead of 150 ohm.

Thus far does not show cop>1 for me.
I need to get the right tranny.

I made this little high frequency bridge and it performs well and can charge an electrolytic up nicely, just included the piccy here because it's a nice little module for experimenting with.

@ EMdevices
Here is a schematic of where I think you are going next. I thought it might save you the trouble of making one. If you mark it up I will update it with your changes (if that would be helpful).

I do not think dissecting it and "proving" that with resistors it's all in-phase, is a worthless affair.

I meant it's not a "worthy affair".
