Thanks so much, Terry!

I rewound the primary of the OSC coil. 16 turns of 38 ga wire. Same direction (clockwise) as the original. When I used a bit of low heat from the heat gun to melt the wax over the original winding to remove it, one turn of wire fell off. Guess I found the break right away! Took off the old clear ring under the winding and replaced it with a strip of thin clear mylar. Now I will be the first to admit I am not very good at winding this tiny wire. There are gaps between the turns. It ain't pretty. Not sure if that matters much if the turns are touching or have a gap between?

When I gator clipped it back in, I get very faint reception when I clip my antenna wire to the ANT clip on the chassis. Pretty much what I was getting when I gator wired in the OSC coil from the model 89 I was trying.

With my newly rewound OSC coil from this set, if I move the antenna wire to the center tap of the volume control, it made no difference. This is I essence Pin 2 or the primary of the ANT coil.

Now if I put the antenna wire on Pin 3 of the ANT coil, or the secondary, I had steady wide open volume and received many stations up and down the dial. So, despite the gaps in the windings, I think my rewound OSC coil is working.

I can measure resistance with the ohm meter on both the primary & secondary of the ANT coil, so either the coil is shorting between the windings, or one of them is partially open. Or the volume control could be a problem...

The schematic shows it should have a 20K ohm volume pot, but this set has one (stamped Philco and looks factory correct) that measures 600K ohms. So I tried one I had on hand that measured 100K so see if it made a change. It didn't.

So I'm thinking I should just let the OSC coil as is, as it seems to be working, reinstall it and concentrate on the ANT coil? I'm guessing, as you thought, the outer winding on that is bad too.
