We All Have Those Kind of Days!

i've not owned an ET2, but on the Rockport that might be a 'level' issue on the arm shaft. and i also used acetone. regarding leveling, it's more that the arm tube is level, not the platter. if it's not level, the grooves will be trying to 'push' it uphill.....and obviously, the platter surface does need to be parallel with the arm tube.

i agree that cleaning is the most likely culprit, particularly if moisture gets into the air lines. then you may need to dry the air tubes with compressed air.

good luck!

Yes sometimes one even needs if this happens to popping the bearing out (it's held in by two o-rings) and cleaning it more thoroughly

Awful I know. I plead guilty of at least THINKING about this at a few funerals. Aaaargh!

Hi Jadis!

Hi Sam,

The issue could be lack of air, whether flow or pressure. Have you tried sliding the arm (with cueing lever up) and feel the slide as it gets near to the 1.5" area? Do you feel any tightness at this area? Like the arm is not smooth moving? That can mean a lack of air. Also, try to feel it at the beginning of the record, cueing lever up, and slide it and see if there is any tightness. For some reasons, this tightness happens at the beginning and at the end. Bruce will tell you to clean the manifold by removing the arm tube first. Then check air pressure. These are normally the culprits.

Sporadically, there is "tightness" at the beginning of the record that resolves with cleaning.
The arm with cartridge slides beautifully until it becomes recalcitrant at that ~1.5" reference point.
Thanks for your observations

Both platter and arm shaft appear correct using a radial level for confirmation. A thorough cleaning is warranted, I suspect, along with fresh tubing and filter...will evaluate the Wisa for PSI.

Appreciate your chiming in

Houston -- we have a problem...

...will evaluate the Wisa for PSI.

Wisa pump outlet @ 5.2 PSI...Airtech Surge Tank Air Reservoir outlet @ 0.2 PSI
Please let me know of any suggestions regarding the Airtech...I realize I could simply remove it from the chain, but I'm interested in effecting repair, if possible

I'll google the web

Thanks.

Hi Sam,

0.2 psi? And that pressure of the surge tank feeds into the tonearm? I think that is where the problem lies. ET2 needs at least 3.0 psi to work, IIRC. As you said, it's simple to bypass the tank and plug the Wisa into your arm. And see how it travels now.
