If the resistor is still in place I would check it's resistance. It should be close if it is still functioning. Really low ohm resistors in older sets are relatively rare. If they are used they are usually found in the primary B+ supply to prevent inrush failure of the rectifiers (silicon). Seleniums rarely have anything but a fuse resistor to prevent the house from smelling "real foul" when they burn out. What circuit is it in?
I have seen low ohm in the filament of some high voltage rectifier tubes but they are pretty reliable in that application.
