Brand new Technics SL-1210GR platter wobble ... disappointed!


Got a brand new Technics SL-1210 GR. Tonearm bearing feels good, no other issues, but it has a wobbly platter. Not as bad as I have seen in Hanpins, but should a $1700 table made in Japan have this amount of wobble? My Project belt driven TT has no wobble that I can see with naked eye.


I have uploaded 3 videos on YT. Can you guys take a look and tell me if this is acceptable for a $1700 TT w/ no cart?

Debating whether I should accept this or return it. I do not want to send a brand new TT for service. FYI, I did reseat the platter at various angles to see if the wobble went away, but no such luck.

P.S. Apologies for a bit of camera shake, but I think it is clear to see the platter move up/down

The deformation is also in two spots,  not one, so it's impossible for it to be a side impact, as that would be one wobble for the spindle, not two unequal length ones per single rotation.

So it appears to be a platter wobble.

the way to check that is to lift the patter and turn the spindle a third of a rotation or half a rotation and then drop the platter back down onto it again, with the platter having done no rotations at all.

and check the wobble again to see if it changes it's character.

Wait... there IS a way to have two wobbles per rotation, now that I think about it. 

Where the spindle is bent and the spindle hole on the platter is stretched and/or the platter body itself is bent. That would be two separate wobbles if not aligned or one big one, if they are lined up. A single sharp hard impact would create the single big one that could be moved about to be two smaller wobbles.
I would not find that amount of wobble to be acceptable on even a used plasticy 40 year old $50 turntable.

In my mind there is no way that technics/panasonic would find it to be acceptable, either.

I just don’t see it.

I’ve probably handled and worked on nearly a thousand turntables.* And I’ve never seen a panasonic product with that much wobble/warp. 

*(I consider myself to be totally 'out' of analog, as I'm down to around 15 turntables. :P )
