How do wire capacitors in series?
Im taking disposable camera flasher circuits (for the 330v caps) and trying to wire them together so that the voltage adds to hopefully around 3000v. But I know that capacitors have strange characteristics and am afraid to wire them in series. Basically How do I get the affect of wiring them in series?
I don't want to combine their capacitance I want to combine the voltage they release when the leads are shorted. I'm looking for maximum voltage, if you have any other suggestions on how to do that, that would help.

Capacitors in series really don't work, specially electrolytic ones.
If you have enough spare power, you can put a shunt resistor across each cap, and then you can wire them in series. The resistor has to be sized so that the current through it is perhaps 5x the worse case leakage current of the cap.
And determining leakage current is difficult. look at the manufacturers specs. If they don't spec it, skip that manufacturer and buy from someone else.

What you are trying to build is a Cockroft-Walton voltage multiplier. You need diodes as well as capacitors.
3kV power supplies are readily available. The cheapest and best way to go is just to buy a used one on ebay. Design is a bit tricky.

nicely its remember on human beings I had used capacitors, it sound louder for bass and verify you hook up next on your amp. in case you have place to place 2d battery and likewise you may desire to purchase battery chop up container(dont bear in mind call for it).
