My s1r9a9m9 replication!

Here is DC-DC converter with 6uF capacitor.
Make sure rectifier diode must be and use high frequency transistor or mosfet with mosfet driver.
1. BA159 for low current (low value capacitor)
2. BY399 for high current ( high value of capacitor)

Initially use bulb to protect mosfet and transformer.  small 25Watt 12V bulb is connected between center tap of transformer and +12V.

Very nice pics. Do you use CD4047 IC like my attached schematic? To protect MOSFET we can connect a resistor serially with a capacitor across primary coil. I suppose you took the transformer from a computer PSU?
Thanks!

Yes

To protect MOSFET we can connect a resistor serially with a capacitor across primary coil.
It's not necessary If coil turns ratio and operating frequency is proper, MOSFETs which I used are having low frequency operation, It works best at 1KHz but transformer required for this is having big size.
Higher the frequency lower the number of turns.

I suppose you took the transformer from a computer PSU?
No, Old TV

Here is some images of my latest coil...i bought the secondary wire on eBay, its rated @ 1000V...so i will make tests and let everyone know if the wire is good to use.(in case you were looking to buy some wire)

First image is the secondary

Second image is the primary on top (its transformer wire form a microwave)

@xbox, 

Thanks for sharing your coil pics, what gauge is the wire ?
