I check  quite a few caps ......from  10pF to 5uF

I, know I really need to expand my cap library

CAN YOU GET IT TO COMPOUND IN THE DRIVEING CAP?

?

LIKE THE VIDEO ON YOUTUBE ... IF SO    TIC TIC BANG TIC TIC BANG .....


IM NO UP TO DATE EE IM AFRAID I HAD TO RELEARN ALL ...  THE MORE CAPS YOU PUT THERE THE QUICKER THEY CHARGE THEN DISCHARGE SEPERATLY ...

Yes it is just like that its behaviour. If you use the light it makes the battery to last longer, but discharges slowly anyway. When the light is out and the circuit is running it charges the battery.

Can you believe if I tell you that mine does not want to work anymore for unknown reasons?

BTW
Can you draw a sketch of the MOT connections to the circuit? That is just in case I find a microwave and take out the MOT to replicate.

The  schematic   would be  a basic  JT   

Here is a picture of the connections

The yellow wires  are my normal  wires for  connecting  my coils
The 2 yellow on the right  are connected to the low voltage coil ..... ( heavier wire )
You  can see the other  yellow  wire  connected to the high  voltage winding  ( thin wire )
The  white wire  replaces  twisting the  2 wires together on a regular JT
Sorry the black wire is  so hard to see ....... it is  connected  to a  tab on the  core .......... ( grounded ).   
The  red wire  coming out of  the  MOT is the secondary ......it is internally  grounded   on the other end ........


I hope you  find  a MOT

Not  sure what  you mean by the driving  cap
Do you mean the cap  used  in the tank   going to the  base ?


I  remember some of that  video  from  quite a while back .
My connedtion is  so bad right now when I  try to watch videos  I can only get 3 or 4 words at a time .     
When I  try  to download them and watch   I get  a message that they  are  corrupted

have a look at the transformers at the top of this page
http://www.amazing1.com/transformers.htm

notice there are no toroids. 

Volume discounts available!
I particularly like this one

2000 volt model at 10ma intended for light sabers

Actually thanks, but...

What I need to do is wrap a toroid with as many winds as I can fit. I did this with a little one, a 3/8" one with 74 turns secondary and got 68 volts. That would lite a 20 led spotlight  if I wanted to make one of those. Hmm not a bad idea.

I should do that with one just a bit bigger. Xee can light a tube with a 2 inch toroid wound like that. I guess there is no end to the things left to try.

thanks,

jeanna
