I can easily get away with no heatsink. As long as you don't saturate the core the losses are almost non-existent, which is the point of zero voltage switching. Using a breadboard is no problem at flyback frequencies. Like Jmartis says it should work straight-away if you follow the schematic. Have you found the correct ground wire on the flyback/ tested it with another driver? Just touch the HV wire to the pins on the bottom of the flyback.

ok when i have the flyback hooked up correctly no current is drawn.but when i turn the power on it pull a few amps.i still get no sparks at all!i guess i need new zeners?because i got some from a moniter circuit board and the dont work either.i am taking the whole circuit apart and rebuilding it!
