I have a 10 year old Sherwood PS 9700. It was fine up to about a week ago then suddenly the turntable cuts out midsong, after a random amount of time (between 5 to 10 minutes). Then If i try to restart by moving the arm back across, nothing happens. Weird thing is if I leave it for about 20 minutes it starts up fine, But will continue to stop again as above. What could be causing this? Could it be the belt? is it just old and had it? Is it to do with the motor? It doesn't feel particularly hot.
