Hmmmm. I was looking at it and I don't think I ever really tried to put it
through its paces... I'm not 100% sure how to tell what pins do what
actually. We have a flyback tester here at work (one of the engineers used
to repair TV's) so I can probably just do a ringing test on all the pins
and map out a likely pinout from it. Short of tearing one apart-- anyone
know a good way to figure out what goes where on an "unknown" pinout
flyback transformer?

That would be pretty neat. Even if you could only make 200 of 'em a $20-30
replacement HV supply could be pretty cool!
