Philco 90 Chassis Restoration
#2

Hi Ed

The primary of that coil is wound over the secondary, and is much smaller than the secondary winding. It can be easily rewound; you will need some 38 gauge enamelled wire for this, along with something suitable to use as insulation between it and the secondary winding.

Get rid of the old insulator between primary and secondary - it is made of celluloid, and deteriorates over time, causing the windings to corrode. Let's hope your secondary winding does not have green spots - if so, then it, too, has been attacked by a combination of moisture and the celluloid itself.

But I'm getting ahead of myself. You will need to know how many turns you need to rewind, and in which direction (critical in most coils such as this). There are ways you can find this out. A good primer can be found at Chuck's site:
