42-355 field coil gets very warm
#4

Hi Karen,

There is most likely, no need to install a new transformer. However, the transformers on most old radios, even Philcos, have a tendency to run very hot at todays high line voltages. A quick way to resolve the issue is to install a 15 ohm 20 watt resistor in series with one side of the transformer primary. That should drop the line voltage enough to cause the transformer to run much cooler and operate in a much safer range. I make this mod to all my radios.

Note: It is also possible to install a 6 to 12 volt buck\boost transformer in series with the primary to accomplish the same goal. It is your choice.

Regards,

Ed
