I've got a major problem with my Turntable at the minute, it is seriously unable to stay at pitch, to the extent after it's been running a while you it gets a major case of pitch fluctuation making it unlistenable. I've tried changing the belt, and I've tried cleaning said belt, and all pulleys and the platter, but I've made no improvement. My thoughts are is the motor shot, or cheaper this do I need to put more oil in the bearing. It spins quite nicely at the moment so I suspect it's not that. Any ideas please is there something obvious I've missed, or do I need to find a turntable expert. Does anyone know anyone in the North-West, preferably Manchester way. It's a Townshend Avalon by the way
