2 yrs ago I worked on my neighbors USC-1. His band The Mystics had a hit song “Hushabye” . After recapping this juke his record sounded terrible (wavering). Other records not as noticeable. With Ron R’s help I tried many fixes. Nothing helped until he said try to see if the TT thrust is correct with .003” play. Mine had at least 1/8” and would not adj with thrust screw adj. The adj screw was hollowed out on the end from wear. Replacing screw and adj fixed the wavering problem. I had to buy 25 screws, so if anyone needs 1 let me know.
