Klondike98, thanks your fast reply.
After reading the links you posted I realized that the 0.7 ohm primary is wound at the bottom of the main coil and I couldn't see it as the overheating softened the wax and allow it to blob at the coil bottom obscuring the primary winding. Once I scraped the wax away I found it and it is indeed open and oxidized. The photo is after I removed it and you can see the color of the coil is darkened due to the heat. I'll rewind the primary and make a new bobbin for it as indicated in the attachments.
The second photo is the AM band primary which although it has a tap winding, the main winding measures 11 ohms and should be usable if I cut off the tap winding lead.
Thanks again,
Steve D
