I think you still have something wrong in your radio as there are lots of similar radios out there that use a resistor or two in the power supply and they are rarely more than a couple watt units and they work just fine. You can be absolutely sure that Philco did not install a 20 watt resistor in this radio originally. Have you done a current measurement through this resistor to see what the total set current is? If not you should as something does not seem right to me.
