Replacement Motor for a Vintage Thorens TD 160 Turntable

How much do you love this turntable, and how much are you willing to spend? If your budget is large, you might consider the eclipse motor and motor controller system offered by SOTA. I think it could be adapted for the Thorens. The ensemble is not cheap. The performance will be far superior to what you had before, in terms of speed stability.

Motors don't come apart.

Indeed.
You have to take them apart.

Slipping? Are we sure it's the motor and not the belt?

My son has done enough checking to isolate the problem to the motor.  So I ask, is it possible to buy a new or rebuilt motor?  Or, are there any shops that can rebuild the motor?

If not, I surmise that the TT is scrap. 

The belt is OK.
