Eric, you must have some miswiring on the speaker plug. Previously you mentioned that you had 360 V on one side of the field and 309 V on the other. It looks like you are feeding the tube B+ supply voltages from the input side of the field directly from the rectifier instead of the output side. The 309 V side should connect to the B+ supply for the tubes. Then you would have only 309 V or less on the tube plates and screens.

The field coil wire not connected to the output transformer should go to the rectifier cathode. The other field wire should connect to the output transformer and the B+ line feeding the other tubes. Straighten this wiring out and I think you will have normal voltage readings.
