Please help with the Philco 71B, my first time trouble shooting.

Most of the time the winding that is open it is the small winding on the outside of the osc coil. This is the feedback winding. If this is the case you can rewind it yourself. Two thing you will need to know. How many turns is it? Usually 20-25t. And the direction it is wound.
Remove the old winding. Wind new winding in the same direction as the old. The original wire was 38G this is not very critical. Any thing from 32 to 40G will work fine.
