Agree with all. If the secondary (B+ to be) winding is center tapped, the AC voltage for each half should be very close to each other. The resistance of the windings will be off some because one half of the winding is on the inside of the core, the other on the outside, but the number of turns are equal.

A transformer with no load, (all tubes removed) should not become more than a little warm if left connected to power for an hour. If it gets hot, there is a short somewhere.
