  Gyula:  I was wondering how you see the calculations on Itsu's device, so far.  80 to 90 percent?  Which can be obtain by any efficient inverter. Of course, no offense to Itsu. As I appreciate his tests and videos, immensely. Along with all his help.

  Well, one of the problems I see, is that these little transistors can't handle 20 to 25v. Not even 12v, without a meltdown. In order to be able to replicate what the Doc has shown when using his SG at 20v, and no ground.
Yet, even he is producing a limited output, no where near what the grid powered bulbs can provide. Maybe half the brightness, or so.   
   I can't even get an answer concerning the proper way to wind an L3, other than on a battery. Although I do appreciate that information, and Lidmotor's measurements on the L3 coil.

   So, if the Doc wants to see other people replicating his ideas, then he needs to provide the needed specs. Or at least close to it. That L3 coil, along with the crystal is the heart of his circuit. Yet, he has given no info on the coil. At least not lately. 
The Doc told me once that, "no use kicking a dead horse", and that I should get a horse that I can ride.
Because I didn't have a scope or SG, back then.  And, I'm still looking for that horse... now that I can play ball. Little league, with my limited voltage SG.
    Sorry guys, but,  I think I need a Snickers bar.

   Itsu:   I don't expect to find OU, either. But, I'm hoping to find something useful and practical in what the Doc has been showing. It would help to know exactly how the right L3 is wound.

HI NICKZ. IT IS NOT ROCKET SCIENCE STUFF, AND YOU BEING WELL VERSE IN ELECTRONIC.
IT IS AS EASY AS ABC..ALL YOU NEED IS A ROUND ELECTRICAL CONDUIT, 15 OR 20 MM,
THEN YOU NEED A PIECE OF 2 M ENAMELLE COPPER WIRE. THEN JUST WIND THE THE LOT
NEATLY ON THE TUBE. THEN YOU SWITCH ON YOUR CIRCUIT. THEN TO TUNE UNWIND TILL YOU GET THE
LED TO LIGHT, AND THEN YOU CUT AND SOLDER, DESMOND IS YOUR UNCLE.

Hi nick,  The MPSA06 was a type close to what was being studied. What we have is what we are allowed to have.
In sorting through that episode we are told to stay tuned. The real transistor is not commercially available. It has an
hfe of 400-750 and a Vbe of as low as 0.17 volts. Most of the projects do not rely on special transistors.

So there was more than what meets the eye. I do see that the Doctor usually socially concerned and careful.
He was still off and on with the big semi conductor people. That is how the corporations operate,
everyone waits on them, sometimes lifetime waiting and never getting past their lawyers that control them.
That is where the high horses roam.

I am not sure everyone followed the harmonics in general. The signal generator can be set to square wave and duty cycle
set to 25 % or 43% so that the width is set less than 50. To see the effect. The (AV) or half rectifier diodes effect can
also reduce the width of the sine. Maybe someone can show the effect of narrowing on the harmonics.
Because the negative resistance oscillator frequency becomes lowers when a load is applied it would be nice
to reuse what is left. If the harmonics behave the job is less difficult.

Gyula. I tested with 100K pot resistor but nothing ! maybe the circuit is fake by Gbluer ?
