Well what do you know? Having looked at it fiercely, in case that might frighten it, I picked it up tonight and found the core was loose!! Very strange as I'd pulled the two bits of core quite vigorously last night and there was no movement!
Anyway, I now have the EHT winding in a position where I might be able to do something with it. The problem is where the lead in wire (top cap of PL81) enters the winding down the side of the former. There was an arcing like the sort you get from the top cap of the line o/p valve and a quantity of smoke. Rather strange it was coming from the start of the winding rather than the high voltage end. I wonder if the lead in wire is not making good contact with the actual winding wire.
I need to remove the thick coating of black wax so I can see what is going on.
I wonder if I can effect a repair?
All the best
Nick
