The antenna coil ... could a tube have shorted and pulled enough current through the coil to fry it a few turns from the end?

I recently restored a 1938 Motorola 9A Ch=9-3 Chairside and it had the first IF coil partially re-wound. I was told by someone who restores a lot of 30's radios that it's a fairly common issue when a tube shorts in the first or second stage.
