I think he is wanting to use filament bias. So to say, applying .01A at 20V and use a smaller cathode resistor. 20V/.01A=2000Ohm biasing resistance. Instead of something huge to give that same voltage but with only cathode current through it( and thus likely requiring a bypass cap ).
And a 2kOhm cathode R would likely find it useful to bypass in any case... :)
