Hi All,
Working on a Rowe AMI JAL and trying to get the tone arm return height adjusted correctly. According to the manual you have to bend the tonearm rest so that the needle clears the gripper transfer arm by about 1/8”. However on the gripper arm there is small metal sleeve at the position where the back of the tone arm cartridge passes over the gripper arm. This little sleeve is not pictured in the original manual. Does the tone arm height need to be adjusted so that the cartridge clears this sleeve or is it supposed to touch it and it is ok to ‘skate’ over this sleeve? Thank you for your suggestions! -Hans

Hi,
The JAL was the first jukebox by Rowe and that little wedge shape was not on the early gripper arms. It was an addition on some JELs and then on all from the JBM onwards. That's why you can't see it. Yes, you have to adjust the tonearm so that the base of the cartridge misses that. I think it is there as a safety feature to stop the stylus getting caught if wrongfully adjusted. If you notice, it is flat on the other side, where it is not needed when the gripper is in the b side position. It's a little ramp The arm must completely clear it. If it hits it the arm will bounce up a bit.
The bending of the rear arm bracket is rarely required, and there is also the bolt in the arm that needs to be adjusted which sorts most of the arm height issues out.
