Isn't filament bias the same as fixed bias?

It doesn't matter whether a negative voltage is applied to the grid or a positive voltage to the cathode, anything other then self-bias with a cathode bias resistor is fixed bias. This is the "most severe" scenario Paul described. If you believe RCA, no more than 10K should be used at the grid.
