Crooked Tonearm on Audio Technica LP120

Post by datsquidoe » 01 Jan 2017 21:34

Recently I had received an AT LP120 as a gift, and I had noticed that the cartridge appears to be slightly crooked.http://i.imgur.com/py9TEI6.jpg Upon closer inspection I found out that it was the entire tonearm that seemed to be rotated more to one side than the other. http://i.imgur.com/LUkgfUx.jpg I didn't think it would matter much as the angle is so slight, however while listening to it through different amps I noticed that every time the left side was louder than the right. I switched the channels to make sure and when I did, it was the right side that was louder. I did some research and found out that the azimuth of the cartridge does affect the balance of the channels and was wondering if there was some way I could fix this, or if it would just be worth it to return the entire TT and get a new one.

Thanks!

Returning the turntable would be the best thing, it should have been checked before being sold. Might be that their QC is not very good or that the arm has been mishandled.

Is the connector in the tonearm loose? You should be able to see if that has rotated or the arm wand itself has. To adjust the arm wand back to parallel there should be two screws on its underside, on the opposite side to the headshell connector. You will need a bent screwdriver to access the screws.

Could be the angle of the photograph, but it looks like the wand has rotated.

Everything is tight and in good condition except for the angle of the tonearm. I'm going to try to get it exchanged at the retailer this week.
Thank you so much for your input though!

Thanks for your post, I just checked the headshell on my ATLP 1240 and sure enough there was a perceptible twist.

It looks as if the error is to do with the fit of the male connector on the AT-HS10BK headshell itself which got past QC at the factory.

Luckily I had a spare AT-HS1 headshell which appears to be spot on, however I have an azumith ruler on order from Ebay to check more accurately.

Inexcusable quality control.
