OK I got it working for those who are interested. The basic problem was that I had it breadboarded as you mentioned below. I didn't think that would matter since it seemed to oscillate even on the breadboard, but when I soldered it up just to try, suddenly it worked! So thanks to those below who suggested that. I also had a problem using my one homemade power supply apparently because it had a ripple interfering with the pulses from the secondary. Anyway, small as it is, it works, even if it doesn't have much power (uses just 57 ma now that it's soldered). Thanks again for all the little helps throughout the site.
