Is the 470,000 ohm resistor on the grid of the power output tube 50L6/35L6 or is it on the plate of the first audio/second detector 7C6? If the plate resistor on the 7C6 is bad then it will not get enough plate voltage to work, it's a very common failure point especailly if they went cheap and used a 1/4 watt resistor instead of a 1/2 watt.
