Hi all,
Long time out, just arrived and rebuilding circuit (with bulbs)

@ Cap70,
I'm a little confused with your circuits.
1.- Diodes
As far as I understand (I?m far from an expert) the diodes in series are each one subject to same voltage and current, so the first fail will reduce the chain strength (as well as plugs and inverter life   ).
Could it be possible that diodes in parallel can better withstand the high potential?
20000 v / 10 diodes(parallel)  = more or less 2000 v each, same distribution might happen on current across diodes?.

2.- Coil
I`m confused, you say... primary with transformer wire (The copper colored on picture I hope) and later about secondary, (don't go for transformer wire ""as shown in picture"") use wire for secondary shown in green color.....
which one is each one?
Sorry if too stupid, I?m quite efficient confusing myself.

Concerning bifilar coil setup, I can?t find straight ferrite, do you think it
could be done with a toroidal ferrite?

Best whishes,

1. Diodes in series makes the reverse voltage breakdown higher (i.e. it can block 10000 volts if you use 10 in series instead of only 1000 volts if you only used one)
2. Dont use plain old magnet wire for the secondary as this winding has a crapload of voltage on it.  Use high voltage wire from ebay or a surplus supplier.

I dont think 30kV HV wire is a good choice. The thickness of it @ 25 turns would be HUGE...LOL. Plus i think it would not induce like we need it to. You best bet is some 1000V wire...you can find that on ebay too.

This stuff should be great...

First thing to try before buying exotic wire is to go to a hardware store and just buy some wire...shouldn't cost more than $2, you should be able to get 600v rated with no problem. You want thick wire for secondary because you will have a lot of current on it, and you dont want to restrict that! The next thing to think about is the size of your ferrite...is it toroidal or linear? This will also determine the size of the wire you can make the coil form.....

You cant get 25 turns on a 1" toroidal  with 8ga wire...   

My coils are made from wire in a microwave transformer.. it is .040" (dont know what gauge that is) I have used it for the primary and the secondary... so far i have had no issues with it. I think it should be rated for some high voltage, coming from a microwave.... AND IT WAS FREE!!!!!

So in order to understand this better, xbox you are not using diodes correct, and that is what u used with the pressure test correct??

NO...i have not used a diode setup in weeks! I ONLY use cap70's coil design!!
