I recently had a company build a replacement transformer for my Philco 18. It was specced out to be 120v primary / 760v center tapped per the Philco 18 code 124 schematics. Problem is that I am getting 420v from each leg, which means 840v total. The company says that they build in 10% higher voltage under no load conditions. Is this acceptable? The rectifier tube is a #80 which I thought was good up to 800v.
