I still have my 20+ year old ST-7. It died 10+ years ago when I tried to use it and the drive tire (O ring) smeared itself onto the rolling drive cylinder. A PITA cleaning later, replaced the O-ring and adjusted the drive angle using the rotary adjustment on the back of the arm carriage and it worked again (it can be adjusted to drive too fast so the carriage precedes the arm across the record). I use my Thorens so the Rabco would need to be serviced if I tried to use it again. I like it's looks but it's high maintenance. I mostly liked the frictionless vertical bearing in the arm pivot and the ability to track records at minimum tracking force. Jeff (I even have 2 old ST-4's gathering dust in a closet) Robinson
