I desoldered the wire going to the tube and left the wire going to the filter, and replaced it with 82 Ohm 5W resistor. The hum got greatly reduced. (I cannot unsolder it altogether as it houses the second and third resistive sections of 970 Ohms). So I think I will replace the whole thing and see if it gets completely cured.........

Are you referring to the candohm resistor? I have read in this model they can develop a resistance to the chassis that causes a hum.
