It finally happened. Regine turned on me. Guess who had to walk her home from work today...
Already at work I had a good guess what it could be; the "modified" coil had been neglected for some time. And right, the cable coming up from the coil was loose.
Only one thing to do: Try to repair. Off with the screws, cut off the stripped cables coming through the Bakelite.
OK. So I get the picture now. The coil has been "fixed" at some point, and the only way to get cables through the tiny holes was to strip them. Wet stuff: WD40.
My fix: Unsoldier old stripped cables, replace with new.
But unlike the other fix I soldiered the cables on to the hole; the way I think it is original.
Backdraw now: If I am to open the coil again, I would need to desoldier the cables. On the positive side: Water will not penetrate, and I would assume the coil is less prone for vibrations.
Now: Did the fix work? I think the picture speaks for itself.
