I would not be concerned about the 75 mA rating because the total power supply current drain of the model 20 is only 72 mA or less.

As shown in the attached service note chart, the total power supply current through the 80 rectifier is 36 ma per plate, for a total of 72 mA. The actual total plate current drain of the other tubes is only 48 Ma, the remaining current being dissipated in the bleeder resistor and associated circuits.
