Is it dry? Almost sound like water got in. Or, nearby lightning made a short through the core. Sometimes carbon traces are very hard to find. If you can get at it, use of some teflon insulated wire is a good upgrade. I use that for all the small gauge windings, and THHN 600v #14 for the ones with only four or six turns. I also prefer the physically larger cores like the FT240. Is this a usual 9:1 transformer? 5/15 turn ratio? Or similar...
