The wife has a 12g Nano Cube, recently converted to FW (hold comments please ;) )

Anyway, it has a 24W PC light that has stopped working. The PC flashes continuousy like it is trying to start. Bought a new bulb, same thing - So I assume the ballast is shot?

Anybody know where I can get a replacement, or something else that will fit under the hood?

Thx - Steve
