    I'm surprised your seller didn't at least try the platter that he brought with him to see if that helped-replacing the spindle is a bit of work, but replacing the platter is zero work.

    How much does yours 'wobble' relative to the video below? More? Less?

    Interesting video, doesn't look too hard to try.

    I think he was in a hurry.

    The platter itself wobbles less than the video you linked to but the wobble is much worse when playing a record. I will put my video on YouTube after breakfast.

    Another movie, without mat or record:



    This movie was taken before the seller had a look at it. I don't think it wobbles as much as this now. I could record another video.

    EDIT: The wobble is a smidgen less now.

    Third and final video (this one has sound!), recorded after the seller checked it out (sorry about the poor lighting). To observe the vertical displacement, I try to look at the margin between the bottom of the platter and the face plate, rather than the dots (as these may constitute an optical illusion):



    The wobble is actually quite small. I'm not sure if that is an acceptable amount of wobble (I believe the correct term is runout) or not?

    I had a look on www.kabusa.com and they have a very low tolerance for runout:

    0.005" equates to 0.127mm in English :) That's a very small amount! I think my platter wobbles more than that. It is a pity I don't have a widget to measure it.

    My options are either to ask the seller to replace the platter - this will hopefully fix the problem with the imperfect lip and will leave me with only the wobble in this video. Or ask for a refund minus costs for his time and trouble. Thing is, I imagine most second hand Technics SL1200 / 1210 turntables will have a runout that exceeds this 0.005"? I maybe better sticking with this turntable and a replacement platter. Alternatively, I could purchase a turntable from a reputable source.

    Opinions greatly appreciated. Thanks!

    EDIT: The sound in the video is from the camera not the turntable :)

    Yeah, I've seen enough. If your seller is unwilling to correct this, but willing to accept a return, I'd go that route. Though these decks were designed and marketed to the DJ crowd, they are still excellent record spinners. What's more, they sold a zillion of them, so you should be able to find one that meets a high standard. Silver lining-you now know what to look for!

    Hope you're having a better day.;)
