Crooked "Wand" and Cartridge on AT-LP1240

Post by carchiav » 22 Jul 2019 08:14

I have been using my AT-LP1240 for a year, but lacking a point of reference (never heard a turntable other than a suitcase-style), I ignored the rampant IGD and lack of bass that appeared even after a careful setup, chalking it up to an inherent vinyl thing. Record after record, brand new and old pressings, I would notice that a majority of them got terrible inner groove distortion just halfway through a side. I just slapped on an EQ but it never really felt right.

Now I notice this. It's the only possible thing that I can identify that's wrong. It's hard to convey as photos but I took both head on so it should give a good idea. Looking closely, the twisty part (wand?) where the headshell connects to the tonearm shown in the first photo is crooked. Subsequently, the headshell and cartridge are also crooked as shown in the second photo. I think that the needle, at an angle in the groove, misses out on the bass frequencies, which explains the lifeless sound I'm getting.

I see two screws right there on the bottom of the tonearm. Can I use those to fix this?

I also worry that my records are now all "ruined". Am I making this into a bigger deal than it really is? Is it even a problem?

You are correct in that this should be straight.
Try the screws.
Put a small mirror on the platter. The cartridge and its reflection should line up.

Cheers,

That definitely isn’t right! If you can’t adjust it using the screws, a headshell with adjustable azimuth might work. You could also shim one side of the cartridge, but that’s a less than ideal solution.

Once I see something like that I can’t unsee it. Must fix.

Just shim one side of the cartage

Something thing like a small fiber washer, such as as is used for mounting PC motherboards etc would be ideal as they can be easily trimmed to fit to fit and are light weight .

Hi, I noticed the same problem today with my ATLP 1240, although less severe.

With my deck It looks as if the error is to do with the fit of the male connector on the AT-HS10BK headshell itself which must have 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.
