AM primary of the antenna coil is now rewound...
[Image: http://www.philcoradio.com/images/phorum...e00009.jpg]
Not the neatest job, but it should work since this is merely the primary of the AM antenna coil.
It is 350 turns of 38 gauge wire. The original resistance of this winding, according to the schematic, is 33 ohms. This one is measuring 28 ohms, close enough.
I checked the resistance of the other windings and they are all OK.
I'll reinstall it in a bit, and replace some more wires while I am at it.
