An experiment...

I made a measurement with the amplifier running at 60 Hz (a frequency that ensures the accuracy of my DVM). With 25V RMS on one anode (which would be 50V anode-to-anode), the loaded 8 ohm tap of the output transformer produces 1.77V RMS. Based on the 6.6K:8 impedance ratio of the transformer (give or take), the secondary should produce 1.74V RMS. This would certainly appear to indicate that the transformer is not the culprit.
