anyone ever replaced the suspension on an old sota table

I think  my old sota star has stretched springs. when I place the clamp the platter bottoms on something, she still sounds great though.
I would think that this would be a job for Sota. They still service their old models, and a suspension tune up shouldn't break the bank. If you love the turntable, I would send it off to them. 

That said, any competent hi-fi repair house should also be able to repair the suspension.
