Was the rectifier tube removed at some point? If so, it could have been reinserted with the wrong orientation. Sometimes the socket holes become wallowed enough a tube can be inserted more than one way. By turning the tube one quarter turn, the tube filament will connect the B+ line to the HV winding of the transformer.
