My 1200 M3D developed a problem a few weeks ago. I noticed the tonearm kept drifting to a spot just outside of where a record starts. It does it with the anti-skate at 0 or at full, the anti-skate works and pulls the arm as it should, it still drifts back to that one spot.
I replaced the tonearm tube with a carbon fiber tube about 1 1/2 years ago, thread here https://theartofsound.net/forum/show...+fiber+tonearm
I took it apart and double checked the wiring and that is not the problem. It shouldn't be anyway as the turntable has not been moved in over a year so there is no reason that the wires would have shifted. But I checked anyway.
I also tried adjusting the bearing that controls the horizontal movement. Tightening it slightly made it worse and loosening it slightly didn't change it.
To me it looks like the horizontal bearing has developed a notch.
KAB no longer sells replacement tonearm assemblies and they are $250+ on eBay (new), and I really don't want to buy one on the bay anyway.
What do you guys suggest?
Thanks,
David
