Well, fried a phot-flash board the other day, so figured I'd take a shot at converting it over to 9 Vdc. Pretty sure I smoked the transitor (its house marked so, best I'll be able to figure is whether its NPN or PNP. Anyway, the original seems to be simply a transister, resister, and small transformer.
Anybody have a similar arrangement for 9 volts to 200 or so volts DC.
