Here there is some people following the s1r9a9m9 replication too :

Thanks for your reply.

You mean to say that you are using only one capacitor on primary side i.e. 500 pF @ 6000 V in place of three capacitor shown in Cap70 circuit? Is that AC or DC capacitor? Can you give me the part number and make?

Tommorrow i will source these capacitor also along with other capacitors, which Cap70 has suggested. Then i will test out the circuit and will let you know.

Fortunately i have one old radio where a linear ferrite coil is available. So it will be a nice idea to test this out too.

Thanks for the test steps. That will be a gr8 help. Can i know what transformer you are referring to? Is that normal 12 volt to 230 / 110 volt transformer?

You have mentioned about using the adjustable spark gap tool at primary side. I think you are referring to secondary side i.e. DC side. Is that correct?

With yours and Cap70 inputs, i think i will be soon reaching to stage of testing the plasma spark for various other tests like pressure test, Hydroxy test, Tero plug etc etc.

With best regards

I am using 4 - 2kV caps in series..the total capacitance is 500pF and total voltage is 6kV....i do have some caps on order for china, they should be here soon and i will test them to let everyone know that these caps will work for Cap70s Coil!

The transformer i am referring too is the ferrite coil you have made...

The adjustable spark gap is on the PRIMARY side...the HV side!

I'm doing some pressure experiments with Luc's circuit. I recently shorted out my coil primary. Is it a problem feeding a coil 140+ volts when it's designed for 12-14? How can I protect it?

Thanks,

Dave

This is from the URGENT topic.....this is why i use Cap70s Coil design!!!!! 

Hi, All!
I am trying to replicate the cap70 coil circuit design too. And I having problems too. 
Any help would be great. Here is the problems (see attached picture of my setup):

If I connect B and C no spark apear anywhere. Guess the HV get "shorted" ?
If I leave B and C separated and get close D to B a spark apear betwen B and D and at A point.
If I turn the LV circuit on the lamp bulb (A) appears be "shorted" (from somewhere not having clue ??!) and lights on constantly. The capacitor doesn't seem to be charging/discharging. If spark occurs at point A no "bangs" gets out on the seconds spark.

Thanks!

@Xbox,

I was reviewing your pressure tests, and i'm curious why you did not achieve better results with the new plug,,,,
I know your new jig is larger, more volume and you said it was leaking air.....Have you done more pressure tests??
Is the jig still leaking??...........Were did you get your adjustable spark gap......

Thanks ,
