The belt looks OK, but it does not snap too tightly into place, which makes me think it may have deteriorated somewhat. I think the belt on my turntable is a rubber "O" ring (it looks like a big black rubber band).Īs for the motor pulley, let me be sure that I know what that is - is it the little spinning wheel that effectively drives the turntable? If so, it is quite small - about as large in diameter as the tip of one of my fingers. Posted on Tuesday, Ma15:06 GMTThanks for the response, John A. But examine the belt and the drive wheels to see if they look OK. If the belt is a rubber "O" ring then you probably can't do that, but then the explanation could just be that the rubber has perished, and now fits into a smaller effective diameter on the drive pulley. It would be a bit of a hack, but could work, depending on the design. But you'd have to be careful and take a look at the possibilities of breaking or derailing the belt. You could maybe put a spacer, like some thick tape, round the circumference of the larger drive wheel, under the platten, to increase its diameter 10 %, giving a lower gear ratio. After that, the speed of rotation of the turntable platten is fixed by the ratio of the diameters of the two wheels connected by the belt, and I don't see how that can change suddenly. It's just possible the motor is running faster for some reason connected with your power supply. Posted on Sunday, Ma18:20 GMTThat's 10 per cent.
