There's a complication in calculating the resistance you'd need. The diode will only be passing current at the peaks of the 60Hz waveform. That's when the filter cap is "topped off" (I'm not talking about initial power up). These spikes of current are about ten times the B+ supply current the tubes are pulling. Again it's a best guess, and adjust accordingly.
