A couple of months ago my friend’s SP10 MKII had the same slight grinding noise at the bearing. At first, he thought it was the problem of either the main bearing or some of the chips under the turntable chassis. However, when we switched the separate power supply to the one I had, the problem went away. It turned out that some of the electrolytic caps in his power supply had gone bad. After he changed all the caps in the power supply, all is well, and even the strobe light, which hasn’t work for a long time already, is now working.
On the other hand, I have a SP10 MKII which has erratic speed due to a bad speed control chip. I was told this is not fixable since even Technics doesn’t have that chip in stock anymore.
