Actually, it is available on ebay for like $40. I'm just a cheapass. Plus I don't like being defeated by 1970s technology.

Also, I really don't think it's the coil itself - it worked so nicely - but I really don't know how to test it, I don't know what to input. Is it ac, dc, 110v, 50v, I just don't know. I'd assume it works like a car's igntion coil, where it has power applied, and disconnecting power makes it spark, but uh, yeah, don't know how to test it.

The diodes all test fine by ohm meter. I'd assume a thyristor is the same as a transistor, but you know what they same about assuming.

The interesting part of the design is that it has to be able to self-terminate. Otherwise it'd keep making sparky noise until you turned the oven off. I believe this is accomplished by detecting the flame at the 'spark plug.' I forget the exact theory, but apparently when two metal contacts are inside of a flame, they act like a diode. Kind of like how a tube works... or something.
