Be a bit more specific. Do you mean there is a lot of play as you pick up the arm and move it into position to be dropped in the grooves or do you mean it is wobbling around while it is actually playing the record? If it feels wobbly while holding it in your finger before dropping it on the record, don't sweat it. That's the way the JMW9 tonearm tends to feel. If it's dancing around and wobbling when playing the record, that's a different matter. It should track on an even keel and the azimuth orientation should remain stable like any other tonearm would.
