Hi group. I'm new to vinylengine after a search for turntable Help. I decided to dig out my old Sanyo tuner and Kenwood KD-3070 turntable. While giving the turntable a once over, I noticed some cracks in the detection arm. They look like pressed counterweights. Has anyone seen this before? I was thinking of putting a drop of superglue on them. Any opinions? They both have cracks but one is hard to see in my pictures.
