For those who aren't aware, neon sign transformers are current limited using shunts. Also, the secondary is center tapped to ground so the potential from one wire to ground is only half that of the full secondary. Or something like that. 8D Terry Bowman, KA4HJH "The Mac Doctor" https://www.astarcloseup.com “...the book said something astonishing, a very big thought.
