Hiya Jinx, If say a 0.6J flash is what you want, run a 5 or 6.5uf 440V polly capacitor (the ones they use for cap start on motors) this will give you a great little strobe. I have built strobes with 22uF 450VDC axial capacitor, 680R 11W current limiter, and a standard trigger with a 4N28 opto driver. Regards, Kat. ____________________________________________________________________________ /"\ ASCII Ribbon Campaign | K.A.Q.
