I cut the end of the tube in 2 places on one side down to the tab and it lifted right out.
Unwound it, found an obvious break, but the 'insulation' was poor along entire length.
For what it's worth, 36.5 feet of wire was wrapped on the small wooden spindle in a counterclockwise fashion.
The coil was labelled with the number 38 on the tape that secured the outer part of the winding.
Not sure how you could ever repair it besides rewinding it.
Gotta order my wire.
