I have had my Gamma 602FC for 2 years now with WISE2086 and its been fantastic. I am noticing some slight play/wobble from the turntable when pulling/releasing tension, its nothing big but there is a little play. I can see underneath the machine 4 bolts but these bolts are inaccessible to adjust. I have also adjusted the small grub screw on the side but all this does is loosen/tighten how the turntable spins around. Is the play/wobble normal or does it need adjustment? Thanks.
