Guys i was searching the internet for the simplest flyback driver when i come up to http://www.geocities.com/teslinasite/flytwinse.html site showing two flybacks driven at once with same driver... sounds pretty cool but he doesnt give any info about what sort of a driver to use can i use a normal driver or do i have to make it bigger maybe anyone got any ideas?

It says "the rest of the schema is identical with that found on powerlabs.org." Since I know the site finding the schematic wasn't hard. Just read through this page http://www.powerlabs.org/flybackdriver.htm and you should be able to make it work.

hmmm from what philer did i can see that he used two seperate ZVS drivers... From the site i got the idea from he uses 1 single driver and uses 2 flybacks as a big single flyback which metod should i use?

I beleive it's the same just use the gate winding for feedback and power for power. Use the schematic vasil posted though. Infact go for the ZVS Driver if you want to spend a little extra, the arcs will be much more impressive.

It should work with a normal, unmodified, driver like that on powerlabs (I hate to refrence Sam for the 2n3055 since he had no part whatsoever in the design, but...).... I would recomend that you try winding the feedback coil arround only one of the flybacks, it should give you better stability (and let you usee flybacks that aren't exactly the same).

The driver is "almost" identical. The original schema was with 2N3055 (too weak), Sam used a MJ transistor, I used KD. Just use the power transistor you have around.
But Mazzilli drivers are the best for high power output and intense arcs:

Sorry for the double post i didnt know. I will start with powerlab driver first and then do ZVS driver. I will only try first 2 then 1 feedback windings. If i use 2 2N3055 transistors in a darlington connection and use heatsing+fan cooling (because i have 2 2n3055 now) i think it should be fine.
