Help needed - broken coil of Koss pro-4aa

Hello friends, and i wish you and your significant others my best for Xmas.

Well, i received an original 1974 headphone, with the plus that it's non working.

I guessed someone else put their hands on it, since the coil threads are broken to the pins, and it seems I'm not able to find where the two threads start on the coil...
How can I solve this misters?

Yes i know about the lifetime guarantee etc., But i really don't know whether this works also here in Europe.

So, the question is, how do I take out two threads at the two ends of the coil?

I try to attach some pictures, hope to clarify how things are.

Thank you again and my best wishes!
