Take a closeup picture of the winding and enlarge it so you can count the turns. Wire gauge is going to be 38. It's important that you note the direction that it is wound as the new winding must be wound the same. It does not have anything to do w/the osc frequency but it's the feedback winding. Replace the rotten film strip under it.
