Theoretically (unless you are checking the heater circuit, or the tube internally connects 2 pins and the set uses that to open a circuit if the tube is missing) it doesn't matter since there shouldn't be any flow between plate, grid(s), cathode, and heater when the set is off...The tube should act like an open circuit.
