If you have the KD990, as mentioned in your other treads, its worth repairing.
They are becoming quite sought after - sale of one would easily cover the repair costs.
Have you tried Time Step in the UK - they mod Technics, no reason they couldn't do the Kenwood I would have thought.
For digitising - not state of the art by any stretch - but have a look at the Audio Technics ATLP120USB - direct drive - has everything you need.
