In my case, I would be very surprised if it was a crossed winding, I think more of an isolation fault on the wire itself + extensive operation of the final stage of the amp.
The guy in question was a very rigorous career soldier with a great winder but tended to believe a little too much in the extreme reliability of the components, or to push them too hard according to different opinions...
I should repair it one day but it stinks so much that I can't get around to it.
