No, both arms- just in a different way.
I just put it on the hearth and the warble in one and the distortion in the other are gone. And now I've returned it to the wall shelf without the discs under the fat spikes so the spikes go right into the wood of the shelf and I lowered the spikes to their lowest level to reduce any play in the shel. It's about 60% better but still warbling and the other arm is distorting again. Or mistracking or whatever it actually is.
This table may be going away until we move in a couple years to somewhere I can fit a proper massive stand.
