Coil Rewinding Service
The coils used in the earlier Philco sets are notorious for going bad. This occurs for two reasons:
the radio may have been stored in a damp location for many years, causing corrosion to occur in
the very fine wire used to wind the primary of the coils; and
the breakdown of the celluloid strip which acted as an insulator between the primary and secondary
windings, which releases nitric acid and corrodes the wires.
I am able to repair those old Philco coils made between 1928 and 1935. Look at this example of a
bad coil, compared with how it looks AFTER I rewind it: (click a thumbnail to see a larger

This old Philco coil shows the classic symptoms of being bad: green areas at the top and
bottom of the primary winding. The green
indicates corrosion of the wire. |

Here you can see how the same coil looks AFTER I rewind it. The coil has a brand-new primary
and secondary, and should be good for many, many years. |
The vast majority of the older Philco coils have the primary winding wound over the lower end of
the secondary, with an insulating strip of celluloid between the two windings. I remove the
corroded primary winding and the celluloid strip, install new insulation and rewind the primary.
If there is any corrosion showing on the secondary winding, I rewind the secondary also. Otherwise
I DO NOT rewind the secondary as they are almost always still in good shape.
I have provided this service for many years, to many satisfied customers.
