AS a TC? or as a HV AC supply to make sparks? As a kid, I ran a 12V filament transformer into a auto coil to make sparks. Just running it as a continuous transformer isn't all that exciting: typical auto transformer is 100:1 turns ratio, so you're getting 1200V out. However, with a breaker arrangement (or, as it happens a door buzzer serving as an interrupter), you get the inductive kick, and can get fairly decent sparks, particularly in a needle gap.
