If I understand your drawing correctly, you are putting your new resistor or choke between the secondary of the output transformer and the speaker. This is not the right place.

Your new resistor or choke should connect electrically between the positive end of the 8 uF filter cap and the positive end of the 4 uF filter cap. The positive end of the 4 uF cap should also connect to the one of the wires of the PRIMARY of the output transformer, the one that does not go to the plate of the output tube.
