:Warren,
: The radio is a Majestic Charlie McCarthy Number 1 radio. I will have to replace the burned out 40 ohm section with a 40 ohm power resistor. I cannot find a replacement L-49B, but it looks like there's plenty of room for it inside the tube. The other section of the ballast is fine. Is this a 10 Watt resistor or a 5 watt resistor (pin 7 to 8)? A 50 ohm 10 Watt resistor worked with no bulb in the socket.

::A 46 lamp, is a 6.3 volt. But is screw base. The resistor of 40 Ohms is the shunt across the lamp only on pins 7 & 8 of the ballast tube. If you just want to test your radio, leave the dial lamp and ballast tube out. Connect a 200 Ohm 20 watt resistor on pins 3 & 7 of the ballast tube socket. Don't know what the model radio you have. But you can look at an Emerson BJ200, it has the same ballast tube and circuit.
