Lidmotor - I build the crystal oscillator circuit with BD243C transistor. the transistor isn't get hot and stay cold with 24 volt input. the current output from DC DC boost converter is 24 mA so 24*24= 576 mW

Lidmotor - Very nice looking output  8)
Have got several transistors here that I call 'mains rated', just denoting their package size and power handling. There has been some success, but generally the hFE is much smaller. An idea, has been to use perhaps a good hFE MPSA18 and send its output to a PNP, somewhat similar to the very efficient 'DadHav' 2 transistor circuit.
Tests will be done with various NPN's and A733 or A1268, but the idea being to use good power transistors as an end result. Thought it might appeal as a route :)

Say, my L2 on the SEC 18 is quite roughly wound. Have you boxed and put away yours yet or could you tell me how your L2 looks on the bobbin ?
A bonus would be the winding direction, because as iQuest has indicated, both the L2 and L3 should be wound in the same direction.
I may rewind it, but then again if yours is the same then it might be how they are supposed to be.

erfandl---Great news about the BD243c transistor working for you on your crystal circuit.  I am going to order a bunch more because they seem to work well on these type circuits.  The MJE181 one works well also.  It works on the GBluer circuit also but I blew one accidentally.  By the way don't expect high light output on Gary's 3 choke circuit.  It is just an interesting circuit to experiment with.  The hot choke problem I encountered also.  One of my circuit modifications had high current running right through one and it almost melted.   
     
Cheers---Lidmotor

Slider-- My SEC-18s are at another location so I can't look at them.  As I recall the L2 (plastic bobbin) coils were neatly wound.  I don't think it matters though.  The BD243C transistor is what is used in my cheap EBay 'Mini Tesla Coil'.  They give you a spare in the kits I bought.  I was wondering about a Darlington type arrangement also. 
    I have been pouring over the Doc's old videos and forum discussions from 2011 when the PSEC quest was in full swing.  Did we miss something?  Is he going to tell us some secrets while he is still healthy enough?  It seems that he is heading in that direction.  I have always wondered if a glowing red led attached to a scope ground lead wasn't the whole story of the PSEC.  What else was going on?

I found the logic circuit of my led lamp, see picture.
The backside reads:  Y&M-TG-5-9W  so probably indeed a 9W led lamp.

Itsu
Hi Itsu,

Yes, the 5050 LED chip is designed for the 60 mA forward current and 3.1 - 3.4 V forward voltage and this roughly
gives 0.2 W power (each chip includes 3 LEDs in parallel with 20 mA current for each LED).  The 0.5 W version in this
chip family is labeled as 5054, so it is already a different type.The converter you show very likely provides a constant
current drive for the 3 LED boards in the lamp and I think the 3 boards are in series connection.
This way the constant current is 120 mA and the total voltage should be then 3 times the 23 V = 69 V DC,
this gives roughly 8.3 W power what the converter should provide.
Assuming a normal 90 % efficiency for such converter, the mains input power should be around 9.1 W into the converter.
Now what would be interesting is to feed a single such LED board from about 23 VDC source to let 60 mA current
flow and see the brightness as a reference for the oscillator...   8)

Hi Erfandl,

Good job with the crystal oscillator. If I see from the pictures correctly, you drive the LED via a single wire coming
from the single layer coil, right?  Did you connect the single wire to the back plate of the LED board?
Would you tell what is the type of the LED board or lamp? (make, power). If you happen to have a second such LED lamp,
then could you drive it with a known DC power to get a similar brightness the oscillator provides?
Thanks, Gyula

thanks for reply. yes the LED drived with single wire. the wire is connected to diodes not back plate. I think its 7 watt LED ( I don't know voltage maybe 120 volt ? ). I cant remember model of the bulb
the brightness is go higher when I connect the DC DC boost converter heat sync to a big aluminum heat sync.

Gyula,

i can measure that the 3 outputs on the circuit board to the 3 led boards are parallel.
So i believe all 3 led boards get normally around 23V.

For comparison on the oscillator driven board (50mA) and a PS (20 - 23V @ 67 - 160mA) driven board see the video:

NickZ and others:  If I may be of help, you can get the genuine SEC 18 L3 coil information you're looking for 'straight from the horse's mouth'.  On the first page of this thread, ramset attached a document
by Dr. Stiffler which provides a very detailed description of the L3 coil construction which starts on page 30.  See Reply #10 on October 17, 2017, attachment file name DocumentSEC18_Rel_2_8-1.pdf 
https://overunity.com/17249/dr-ronald-stiffler-sec-technology/10/

iQuest,

thanks for the heads up, so the below picture shows the data on this L3 coil.

I rolled my own also on a 16mm diameter former with 70 turns and it comes very close to the 26.6uH

Guess i have to make another 2 exactly the same for things to come.

Dear Itsu,
Many thanks for doing this test.  I did not stress it enough that the critical parameter that should be kept for the
5050 type LED chips is the 60 mA forward current and if this is observed then it functions as specified, the voltage
across the chips is secondary question because it may range from 3.1V to 3.4V chip by chip.  So the 23V I wrote should
indeed be reduced to as low as to let the 60 mA flow, not higher.   

I mention this because as you found even the 20.3V drives already higher than 60 mA forward current it was 67.1 mA and
surely the 7 mA extra current increases brightness.  So you may need to go even below 20V to get the 60mA input for that
LED board.
May I notice one more thing: Does not the oscillator excite a little better the LED board if the common point of the diodes is connected to the negative  rail? Or the piece of wire hanging on it insures even higher brightness?

Thanks again.   Gyula

Hi Erfandl,

Thanks for the pictures on the LED board, unfortunately I have not managed to identify it.  No problem of course. 
Yes,  the EM field is relatively high when an unscreened air core coil that size (tuned a little with a ferrite rod) and
everything influences it that is nearby, including metal objects.   As if the metal bodies would atteact such fields,
it looks like.  And of course our hand and out body also influence the field of the coil, even detune it.

I would suggest to use an electrolytic capacitor across the positive and negative wires of the LED boards, to filter
a little the output of the two AV plug diodes. Any cap from 47 uF  (microFarad) and at least 160V DC rated would be ok.
This may also increase brightness.  The increase in brightness will not be much though but a small increase can also count.

  I tried using my function generator to transmit energy wirelessly by using my old Stiffler towers.  It worked.  The towers were setup to work with SEC 15 or SEC 18 units that ran at around 13.6 MHz so that is where I set the generator.  Here is what the experiment looked like:

That's another great way to ensure a match of output and receiver, by using exactly the same top loads. Have just watched your hallway vid again of these from a decade back and realised an advantage of the time gap, I could watch it for the first time again LOL
Jonny Davro had repeating towers all across his kitchen, it might be an idea to repeat that experiment but put them in a circle as a current loop.
Am wondering if a version of that, at a distance, would work more effectively than 1 receiver.

The AD9850 replacement module arrived and has been soldered into the frequency generator build. It's now also been tested.
All works great.

Shown with the scope running, as the amplitude and peak to peak voltages are measured through the 0-30MHz range.
Output is very low, even though it says 10.5V pp on the scope at low frequencies.
However, there is a little wireless output using the original SEC-18 L3 in the higher MHz area.
Amplifying is the next part up to 20V.
