Somewhere I have the winding data for the John Folsom replacement parts. The details seem to match closer to the Westinghouse 15" transformer, but the basic operation is the same: 1:10 step up ratio with a secondary having a tap around 1/3. The winding resistances are not critical here because both windings carry very little current. The problem with the original parts is the same as all the vertical output transformers going bad now; the older materials have not held up and are breaking down under voltage stress.
