I'm trying to rehab a Sherwood ST 903 fully auto linear tracker and I have only one glitch left to conquer: I can get the arm to pick up and return at the end of a record. If I track the arm all the way to the left with the arm lifted it does return. If I hit the reject button, it returns. Since I can't find a service manual, I thought that someone here might have some advice to impart.
Thank you in advance.
