I have begun restoring a Philco 38-12 radio and have a question that I hope I can get an answer to on the phorum The speaker in this radio uses a field coil with a resistance of 1.5k ohms according to the schematic. I have completely disconnected the coil from circuit and when I measure the resistance I get approximately 6k ohms on my multimeter. I have been told that the 1.5k ohms shown on the schematic is the impedance of the coil and not the DC resistance. I restored a Philco 39-6 and the schematic showed 1.7k ohms and the coil showed approximately 1.7k +/-. So my question would be, is the coil shorted and needs replacement, or is it ok as it is?
