What is happening

Help!

I got a used ATLP120X awhile back after scoping one for a long time, and really don't like it as much as I expected.

I replaced the needle immediately when i got it, and balanced the tonearm. I've played around with tracking force and anti skate, even adjusted the height of the tonearm.

No matter what though, I'm consistently running into issues with records in excellent shape popping and skipping and the needle shaking uncontrollably, as seen in this video. I'm confident that it's not an issue with the records because they play through perfectly on other turntables.

What is happening?
