Hi Aaron & welcome to Beoworld,
on the Beogram 5000 there is a small grub screw at the back of the tonearm pivot which adjusts the travel height. Be very careful though as a small adjustment will make quite a large difference. It's a while since I've worked on one of these but I believe a small clockwise turn will make the arm travel higher. This screw is also made from plastic and the head is very easily damaged so a good fitting small screwdriver and care is required.
Chris.
