      I might have solved it. Dissolved most of the visible hard grease using CRC 5-56 (similar to WD-40 I think) by applying a small amount on a Q-tip. Cleaning away as much as possible and wiping the excess off with some softe paper. The piston now moves freely inside the shaft. I finally added a small amount of new grease (teflon based bike grease).

      Did another adjustment of the Pickup Height and it now seems to work well.

        I think I got a bit furter in the investigation. See attached image. The mechanism to raise/lower the pickup arm is the brass shaft in the middle of the picture.

        The grease (green) is old and it is very hard to move the piston inside the shaft up and down (I have disconnected the arm controlling the raise mechanism, it’s the long arm with white plastic at the end behind the brass shaft).

        I guess I will have to get this piston out of the shaft, the piston is called part 1576 in the service manual. It seems very hard to get this piston out. I will have to dismantle the whole record player.
