P3-24 pitch instability

Unfortunately, that wobble is common with the newer rega tables! Last year I bought a P5 and noticed the wobble. I took my table back to the shop where they contacted Rega, and Rega sent my shop a new motor and pulley. Same wobble with the new motor! I then looked at all of the Rega tables on display in the shop, and all of the tables had that slight wobble like your table. I do have the TTPSU, but that does not affect the wobble. I can not hear any effects from the wobble. My table sounded fine with both motors. However, I did have the same concerns when I saw the wobble. I wish our tables didn't have the wobble, but my table sounds great to me!

The first video clearly shows that either the motor shaft is slightly bent or the more common problem being the hole in the pulley has cylindricity error. I would bet that is the case. The only way to fix it would be to get a new pulley from Rega.
The second video shows that the spindle has been pressed on at a slight angle, although it does look bad, it won't have much affect on playback. THe subplatter assembler didn't use much care when putting the spindle on. The pulley issue is defintely something Rega should acknowledge and fix.

I haven't had the best experience, Elizabeth, but I don't think it should write Rega off. I still get the impression that they're a good company and these sorts of defects are bound to happen. I'm just unlucky.

I checked my recently purchased P-5 last night. No wobble at all from either the spindle or the motor, or at least I can't see it by eye.
