Moerch UP 4 setup uni-pivot ???

Hello nrchy,

When you say the tonearm rotates, do you mean that it rotates laterally when you lift it with the arm lift?

If so, you might try rotating the counterweights (not moving them forwards or backwards but rotating them clockwise or counter clockwise) to achieve lateral balance.

Do you mean drifts to the right? (counter clockwise) when lifted off the lp?

Any arm, with anti-skate applied, will drift to the right, as it has outward force, say 1.5gm, while when not in a groove, playing, the inward force the anti-skate is compensating for is absent.

The texture of the lifting arm will influence how much, or none, and if you lower the lifting arm when outside the lp's edge, the outward pull will be readily apparent.

This is why anti-skate should be set to zero when setting tracking force, then apply anti-skate.
