It should be an easy fix. I seem to recall that the primary for SW (the 0.7 ohm winding) is only a few turns of #37 or 38 gauge wire on the outside of the coil, while the AM primary is a couple hundred turns on a bobbin mounted inside the coil, near the top. In which case, you are lucky. I've had several of those coils cross my bench where the AM primary was bad.
