Nice. The high voltage wire for neon glass is GTO wire, usually rated 15,000 volts to ground and number 14 gauge stranded. The preheat F15 conversion is nice, the ONLY way to go with fluorescent. That Jefferson core and coil neon transformer is an antique! Just be careful of these non potted transformers as they sometimes like to overheat and statt giving off the burning up ballast smell and will burn up if they do. I have had more than one do that to me! This transformer is either a 4000/18, 18 milliamp low current one or a 4000/30 30 milliamp standard current one. Judging by the low intensity of the neon, it is probably a 4000/18. The voltage of it is about right for that length and diameter of argon/mercury filled fluorescent phosphor coated glass. The voltage of the transformer used doesn’t matter! The current rating is fixed and the transformer will “choke down” to the voltage of the total length of the neon glass and will NOT become “driven hard” at all. Only a higher milliamp rating can do that. So a 15,000/18 or /18 will run the neon fine, though choking down to the voltage of a small length tube, especially an argon/mercury one with more conductivity will cause the transformer to be “under loaded” and will have high losses that make heat that will eventually burn the transformer out. So no worries about over driving a neon sign. Cheers! 👍🏻😋
Nice preheat conversion.
The 2 switches, Fluorescent or Neon or Both great idea, In the UK would have wired it a little different as we don't use wire nuts. Cool Video 🙂
