That's exactly the problem I mentioned.
You really need to manufacture another hook or peg on the tonearm carriage to reaffix the nylon line to. The original plastic hook has snapped off and there is no way of glueing it back on even if you still have it and it is quite difficult to see where this hook originally was. Then there is rethreading the nylon cord for which you really need the schematics. To be honest, even with the drawings it is pretty difficult to figure where the hook originally was. There is a thread on here somewhere with photo's of the repair but I can't find it at present.
If you lived a bit further North or know someone who visits Leeds regulary I could easily sort it for you. I wouldn't recommend posting it as these simply don't travel well at all.
Chris.
EDIT _ nice one Mika - I should have realised it was one of your excellent repair jobs. You posted as I was typing away & trying to find your thread Ian - you are already half way there as far as this repair goes.
