I have a couple of Variac cores less the mechanical wipers. I was
thinking of using the Variac as the primary winding and winding the secondary transformer over it.. I have my own ideas about how I would procede with this starting with given the old coil a new insulting coating, maybe Krylon HV coating . Secondary would either be wound for 540VAC or twice that. The transformer this is replacing was a 540vac transformer feeding a voltage doubler. Any ideas and suggestions would be greatly appreciated. |
