I have been designing a spark gap tesla coil, so far trying to use what I have to save cost. I currently have a solid-state NST and I have read that they don't perform properly for Tesla coil applications (I imagine sudden current draws create back emf that is bad for the transistors?). I have...
I was reading some information about electronics and I have found that some neon sign transformers, if not all, have a cable that I don't understand why they are in the NST.
I put the picture to understand better the question. The cable I'm refering to is the white one. Why does this cable?
