Hi,
I'd say the voltages are way too high. Especially the 300B Filament at nearly 8V.
The hum comes probably from you either having disturbed the grounding or from the magnetic field of the new transformer being much stronger than the original one and being picked up. Did the orientation of the transformer change?

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
