When a resistor replaces the field coil choke in a power supply filter you loose the filtering effect of the inductance. So to compensate you can increase the value of the filter caps. There's a limit to the amount of capacitance of the input capacitor which is found in the specs for the rectifier tube. Hope that fixes the hum.
