The crutchfield resident tt expert I talked to said this amount of wobble is "normal" with these tables. Which means if I exchange it, there is no guarantee of receiving a table with no visible wobble. Or if I send it to the factory, they will send it back saying this is within normal tolerances. He said most do not complain.
So I know most of us think it should have no visible wobble, but many do. Unless some SL-1200/1210GR owners can tell me they have a table with no visible wobble.
