Some of the paper not seen in the picutes I posted are a dark brown, and it looks like some of the wax ran out of the transformer at some point. I dont know if that burnt up canohm hurt the trans. or what ever caused the candohm to burn. The bottom tap (candohm) which was closest to the burn is connected to the center tap of the 80 plate winding.
