   I would suppose that the idea with using the SG is to find the resonant frequency sweet spot, but, later do away with the SG.
   Therefore, a proper circuit that generates the right voltages 20v, and correct 13.5MHz frequency need to replace the SG.   What would that circuit need to look like??? And, the frequency should not be just a stable 13MHz, either. As it needs to be a controllable frequency, to adjust for different lodes, and changing ambient, like varying day or night conditions, etz...
    That is my question. What would that particular circuit have to look like? 
    The Docs not there yet, either. But, I think that he's headed that way, sooner or later.

I found a110v bulb that works pretty good----at least working off a SEC 18.  It was too late in the day to try it on my 13MHz crystal oscillator.

Some 13.3mhz xtals can be found in old Sony TV remote headphones if any one is interested !

Lidmore any chance of a photo of setup re bulb. Chears
PS forget it as your video is now available,    no problem

Hi Lidmotor,

Very good, congratulations and I also think you replicated the effect i.e. exciting p-n junctions of SMD LEDs by strong RF field via capacitive coupling.
Suddenly I cannot recall what frequency a SEC 18 board is working at? Is it within the 13-14 MHz frequency range? With a loosely coupled scope probe placed nearby the air coil may pick up enough juice to display the waveform hence the frequency.

A suggestion if you have not tried: just connect the center of the two diodes with a piece of wire directly to the negative supply rail of the oscillator instead of to the surface of the metal block (remove that block). The Doc showed this connection in his video a month ago with a SEC, video time 1.38 : https://www.youtube.com/watch?v=PIcaDtSUT3I

Another component that might be useful for this kind of thing is the Hitachi 1SS106 diode.

Hi TK,
Fine, thanks.    (The only drawback though is it has only 10 V reverse voltage ratings.)
The Ge diode types like OA161 or OA182 would perform also well here.
