I was able to remove what remained of the coil wire and nitrocellulose.  Still have continuity on the secondary so guess I am good there.  I will follow the procedures outlined in the above reference but avoid the ammonia.  Any recommendation on cleaning other than ammonia? I counted the turns at either 13 or 14 - hard to tell because the wire was in a lot of pieces.  Does that sound about right for the number of turns?
