Wow/flutter issues P3-24 — measure motor accuracy?

I've had this issue with the table as long as I've owned it. I've replaced belts, re-lubed the bearing and have had no success. I'm wondering if it's the motor.

Is there a way to check that the motor is spinning at a consistent speed? Like, I'm just going out on a limb, take off the belt and use a multimeter to measure ______ to see if it's consistent?

Did you buy the TT new or used?

If you bought the TT used the motor pulley grove as well as the platter, where the belt rides, may have belt residue buildup. Residue build up will cause wow and flutter.

I had the same problem with my AR TT. Cleaned the motor pulley, sub platter where the belt rides, and washed the belt with dish soap. I also stopped using talc powder on the belt.

Note.... Be careful when you clean the motor pulley not to get any cleaning solvents on the motor shaft that could migrate on/into the shaft bearing. You only want to clean the grove.....
I used several slightly dampened cotton swabs. I couldn't believe all the black gunk that came off on the swab.
Don't worry, there are lots of very, very expensive Turntables out there which can't hold the correct speed. When you want to check it (also in future for your next one), the best tool is the Timeline Strobe from Sutherland.
