Russell, So this transformer must be using some type of metal besides=20 Mumetal. It is a moderate voltage, high current, 60 hertz, power=20 transformer. I decreased the voltage of the main secondary winding by=20 half and I doubled the current capability. I also replaced the second=20 secondary wire with a larger size. This increased the current capability=20 but the voltage remained the same. Thanks, rich!
