Gripper Arms

You can always learn something, can't you?
Looking at my Rock-Ola 443, I noticed the gripper on the tip of the arm wasn't exactly level with the edge of the record as it played. The point of the "V" seemed to be slightly higher. I checked my 468 and this was the same. Then I watched carefully as it removed the record. The "V" being slightly higher meant that as it moved to grip the record, the lower flange of the "V" lifted it slightly before it gripped. I couldn't see it being a fault on both. So I worked out that as the gripper arm raises the record in an arc, this was to ensure the record centre lifted cleanly off the turntable spindle.
