Your only hope, if you want to fix this problem without spending money, is to try the method suggested by GK. Otherwise, you have a platter that is not flat. A flat platter is a core requirement in vinyl reproduction. If one of your rigid mats lies flat such that it is plane parallel to the arc inscribed by a tonearm, then you might get away with using a rigid mat. Otherwise, I would dump the thing.
Platter wobble
I have a Technics SL-BD20D and the platter has a noticeable wobble while spinning. ive tried a couple mats - cork and acrylic - which made the wobble much more apparent. The rigid acrylic platter would not lay flat on the platter.
Anything I can do? Is there a way to test what the issue is? Is there an quality aftermarket platter that I can use?
Thanks!
