Mijo, On the Wally site it suggests not to use the anti-skate bands on certain test LPs. I don’t know whether that would include the one you recommend.
I am also gratified to read the following paragraph on the Wally site:"IMPORTANT: Using a blank record or the groove-less area of the inner run-out on a record to adjust anti-skating so that the tonearm remains stationary is not a recommended method to adjust anti-skating as it results in about 50% too much anti-skating force applied."
This is an advisory I have given to many,including the OP. Take note, OP. Also, the point made by the Wally site, that there is no single perfect setting for AS, is why I suggest setting by ear, starting with no or very low AS. At that point you might hear R channel distortion. Then adjust the amount of AS upwards in very small increments until the distortion goes away, and no further. One cause for your finding might be something dragging on the pivot, causing it to behave as if it has high friction which resists the skating force per se. Check tonearm bearings.
