i will give u a background of what i have done..
I stripped out the AC part of a 200w AT computer power supply to eventually put a computer in my car (my 1000th attempt).
I tried making power supplies from regulators for the mainboard because it worked for my hub. (unsuccessful)
Now, I have measured the output of the bridge rectifier and it's 330 volts
Why not use a transformer to reduce the voltage ?
Anyway, I have come to the conslusion that I need to supply around 300DCV at around 750mA.
I have found this circuit:

I have replaced the diode with a zener, everything works fine. I looked in my "Dick Smith" catalogue, the aussie equivalent of "Radio Shack" for a high voltage zener but unsuprisingly no luck. Are they manufactured at all ?
If u can't then I'll have to wind a very long coil... and it won't be as stable
how can I impement a pass transistor on the above circuit ?
I tried a similar method to which voltage regulators use with no luck
