By the way; you did have an 8 ohm dummy load connected across the OT secondary when you made the measurement, right? Because first of all, it could be bad for the output transformer and/or output tube if you run it without a load. And also, who knows what voltage the secondary would develop if you run the amplifier to clipping without a load.
And, incidentally, if it really had been giving 48v peak-to-peak across an 8 ohm load, that resistor would have been getting very hot very quickly, with 36 watts being dissipated in it. I assume it wasn't getting very hot?
