46-480 Burned Resistor
#1

I have a 46-480 radio that I have been working on for a while. When I got the radio, it did not work and I found a burned up resistor. In the Philco service manual it is R308 and R17 in the schematic published by Rider. The value is 1K and it looked like a 1/4 watt size. It was replaced with a 1 watt resistor. The radio was completely recapped and the tubes tested. I can tune in AM stations but the resistor gets very hot and starts to smell after a minute or 2. The radio also motorboats if I turn the volume up too high.

Any thoughts on what could be causing the resistor to continue to burn up?

Thanks in advance for any advice.
