Electromagnetic Speaker Replacement
#5

I volunteer at the Radio and Television museum in Bowie, Maryland. I got back to the Philco 89 code 123. I replaced the field winding with an 1100 ohm high wattage resistor, added a permanent speaker and the radio is playing. I will probably add a choke coil for filtering. I need to check the alignment.

Thanks to Terry and Texas Rocker for their suggestions.

It appears that the field winding shorted out. It was black in the outer layer of the windings. Appreciate all of you help and suggestions.
