Thanks Resonanceman about the diagrams. Can you please tell me about the large cap where to connect it is it there as indicated?
What are those coils flying alone? Are they connected with each other?
Thanks

The cap  you circled  1uF
Mine is  rated  at 250 V
You can probably  get by  with a lower rating.

A larger  cap  would buffer  the spikes more.
A smaller cap may actually  increase  the voltage of  the spikes a little .


About the coils
Back on  reply 9962  I have the drawing  you  used in  your reply and another drawing
The  reason for those drawings was to show  how to connect  those coils  to reach  a self charging state. 
The black  in those drawings  are the original JT and  the extra JT coils that are being  used for  flyback  and  feedback .
The blue is  the Jesus  charger .
The  red lines represent  wires  used  to connect  the  coils for flyback .
The  violet lines represent  the wires used for feedback .
I did 2 drawings  to try to avoid   it looking like a jumbled mess.
The  real circuit requires BOTH  the  connections for  flyback and feedback.

10  extra coils  are shown .    I  have  usually needed 7 to 9 JT coils  to reach  the state of self charge .    ( both  battery voltage and output  voltage rising )
You will need a pot in place of the  resistor  on the base of the transistor .
I can not  claim OU  with  this yet ......because  it is not quite stable .
It  will self charge for a few hours then  it drifts out of resonance or something.
A simple  adjustment of the pot  will  put  it  back into self charging  state for another  few hours .

@all And Pirate

I think now is time to start a second tread for the jt , since pretty much every confirmed the potential i have seen in this project months ago .
congrats everyone !

Now is time for the  Second Stage jt tread Or SSJT ...

First we should include some idea on what that should be .

Ex
first jt really fast charge small caps to high voltage quick discharge into SSJT and see what we can do at about 60 cyc ...

Or go hair pin circuit with spark gaps (on the flyback jt)

A lifter project would be really nice  ...

Any way lets start SSJT talks! I can't wait to see this one !

Maybe I missed it in one of your posts and I didn't see it on your drawing but, what battery are you using to power your circuit?  If it is an AA battery, or similar, I was thinking that maybe you could substitute a supercap for the power source and, I am only guessing here, maybe it would stay in resonance because the cap would maintain a constant value as opposed to a battery?

In other words, charge the cap from a battery, and then run your circuit from the supercap.  I don't know for a fact that the supercap would perform in this manner, but I strongly suspect that it might.

@IST and All .
            Experiment 2 : same JT as before . using a 650farad cap charged to 1.420 volts charging another 650 Farad cap to a charged state of 1.000 volts . This was to save some time and Confirm Over the unity of the run cap . Circuit adjusted to 11 ma input current . BTW an easy way to measure current in put a one ohm resistor in series with positive or negative run battery/cap lead . This way you do not interfere with the circuit operation and can accurately measure the current draw by simply putting you amp meter across the one ohm resistor .
So far the charge bcap is 1.257 and the RUN cap is 1.417 V .
i will stop the experiment when i get the charge capacitor to 1.5 volts . this will be over unity . then i will swap the run and charge Bcap and measure what i have then.. This is a very simple way of showing  Over the unity (OU) Exist .Also the cap i am charging was charged to 2.6 volts from yesterday Experiment # 1 . I discharged it to 1 volt using a small Nicrome heater element which glowed brightly for 4 and a half minutes before the cap reached 1 volt . I lit a cig with it and it was HOT!!!!!!!!! I could have tripled the Nichrome wire coil and got about 15 minutes short before i hit one volt and that my friends is pure AMPS .I may be the First one in history to actually make a heater from a Jt and a BCap . running from an aa battery If i had High Speed i would be the first to post a Video of such a device, SOMEONE replicate this Please . below is the Diagram for the AA setup . It also puts an excess voltage out on the secondary and provides Light and Heat .I am going to improve the JT circuit with bigger torroids and more wire soon . All 1 volt system

I would like to see  you  add a secondary and move  your  heater circuit to that secondary ..... it should  be  even more efficient .

bill that is i think the best thing i ever herd you say !   and not that all your ideas and contrubutions to this are any less... 

but that is spot on !



MK1  bro ... 

that is a wonderfull idea!   chapter !!

the SSJT  lol lol lol 

LOVE IT  WE HAVE TOPPED 1000 PAGES ... WELL AS CLOSE AS I WANT TO GO .. LOL 

999 IS A GOOD PLACE TO CALL INTERMISSION BREAK 

world peace!  LOVE ALL LIFE
