I'm using tree per leg fot a higher voltage rating, just to be safe. Almost evrything I build is overrated. It's always handy to overbuild it since this psu can output a voltage in the KV range, at least when running at 30+ volts. Two of your diodes in series would do fine if you're ain't going to use it at higher powers in the future. You can also build a voltage doubler if you're in need for even a higher voltage.

I'll probably stick with this voltage for now, I think there is a bigger need for more capacitance... But still, say I want to double up the voltage, is this what I use? Thanks a great deal for all the help, really! I'll go build a rectifier and see what happens... That mosfet on my flyback driver circuit that I said was broken did indeed heat up very fast, but now it magically works again. Weird.

The voltage doubler circuit is ok to double the charging voltage, but the diodes should be rated twice the input voltage. The caps need to be about 4.7 nf because they'll get charged en discharged rather quickly by the high operating frequency.

Just looked in on this thread, sorry for the late reply.
IF you parallel the outputs of camera flash chargers you CANNOT series the inputs because The -ve battery connection is also the +ve capacitor connection The net result will be to put the entire 12V (or whatever) across ONE charger ... POOF !!
