AR 77 Xb tonearm issue

Post by jimkarl » 30 Jun 2019 03:52

The tonearm on this table is not swinging as freely side to side as I think it should. As a result, when it hits a scratch the record repeats in that section.
There is a little plastic white "cup" or "sleeve" that the base of the tonearm goes through. When this sleeve is flush with the base, it seems to bind up and the sleeve becomes (mostly) static in position. The arm still moves inside the sleeve, but with a amount of friction (even with grease lining the sleeve.
If I raise the sleeve up such that the lip of the sleeve rides atop the base, it seems to act fine, though this doesn't appear to me as how the sleeve should be positioned. I have another ARxb table (non 77) but it doesn't have this sleeve so I have nothing to compare it to.

I've never owned an XB - only the XA. Can't you remove the white "sleeve" by gently removing the tonearm? You stated your other XB didn't have the sleeve. I hesitate to answer since I've never owned one. You can ask the question over at AudioKarma https://audiokarma.org/forums/index.php There are people there that know the XB well.

I looked at pictures AR (77) XB s on the internet and none had a white plastic sleeve there. Maybe the previous owner thought the tee-bar was shaking around too much...
