The transformer is custom as it serves double duty as the lamp ballast and thus has a deliberately high series impedance, so you probably won't find a COTS replacement. You could use a generic bug zapper transformer and separate preheat choke ballast for the lamp.
Do you know of a video that shows how to change the transformer on the flotron? and possible compatible replacement, the flotron site dont offer them.
