Before I go and do all that, would you guys look at the photos I just put up of the pin and strap, and see if you think it's even possible? To me, the gap between the pin and the strap is a little bit too large. The two photos are in the folder called SC503 CRT.

A photographic strobe charger will work fine as well. If you do not
want to build one, then you might find one in a junked camera that you
can use.
I might try using a small power transformer to step up the output of a
function generator or oscillator with a multiplier on the output.

Well, take the 120 volt AC line into a X2 Cockcroft-walton multiplier will get there if you are careful. For less fireworks, use an isolation transformer and a fuse :).

Tom,
There's about an 1/8" gap between the pin and the strap. Might be possible, but I also don't really have a way to charge a 450 V cap... ;-)
