I used to have an AT LP60 turntable and at one point I realized it was too fast when set at 33 1/3 for most of my LPs.
Disclaimers:
I am not an expert and obviously not an audiophile.
I am OK with my LP60 and I suspect there are at least a few people here who feel the same way and may have this same problem (someday).
If you are an audiophile and hate this TT, please go read something else. This post is not for you.
OK, so, I realized some of my records sounded too fast recently and here’s how I fixed that:
I downloaded an app to determine my TT's speeds.
I have an android phone, so I chose RPM Speed & Wow from the Google Play store.
There are iPhone apps out there too.
It's free and easy to use and very quickly shows you how fast your TT is roatating.
This is not perfect but again, close enough is close enough for me.
Mine showed 34.9 at first (when set on the 33 1/3 RPM setting).
Remove any record from the TT.
Carefully, look under the TT for the two holes marked "33" and "45".
Find a very small flat-head screwdriver.
Use that to gently poke through the fabric covering inside the 33 hole.
Very, very slowly and gently, seat the screwdriver into the screw inside that hole without turning it.
Turn the screw but only very, very slightly.
Seriously - a TINY turn is probably all you need. Less than a quarter turn for sure.
Turn it clockwise to make the table go faster.
Turn it counter-clockwise to make the table go slower.
Run the app on your phone again to test the new speed.
Repeat the adjustment until you get a result very close to 33.33.
Repeat this whole process for 45 RPM if you want to.
I had to repeat this adjustment about 5 times, making ever smaller changes to the screw’s position before I got 33.34 from the app on my phone. Just make very small changes every time and you’ll be OK.
The result is noticeable. I am very happy with this change and I hope this helps someone else.
TL;DR: AT LP60 turntables are good but not great turntables - and there’s no fixing that, but you can adjust their speed. It’s free & easy to do this. It’s worth it too.
Wow this is something that I had not even considered as a potential issue
It sneaks up on you. Not sure why, but the electric motor just won’t stay at the speed set at the factory.
I copied this post from my account on /r/vinyl and I even had people say in there that they found their TT was too fast right after buying it new.

They may be intentionally set a little fast as-new. This could be to compensate for expected slowdown associated with aging of the unit. For example; running 2% fast from new might be less noticeable than running 5% slow after a couple of years. This is just a guess, though.
