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

@lewm, You are probably right about the Crutchfield representative and that platter sneaking by QC. But, it did get by and I would bet there are plenty of warped platters out there that the consumer is not noticing because they are not that critical. Did I tell the OP not to get another one? Did I tell him to get a different turntable? I am not trying to scare anyone.
@tyray, A heavy thick casting is not problem but a light thin one can be.
Also, castings can be unpredictable. I would bet that under normal circumstances quite a few platters do not make it by QC. Forged aluminum is more predictable than cast aluminum but too expensive for a low budget one. 

Mijo, Sorry to pick on you.  But your (belt-drive, suspended) bias was showing. Do you suppose that stuff like this never happens with your favored brand? Probably it does not, I would guess, because they sell way fewer turntables compared to Technics, and they may be able to assemble and run every unit before it leaves California.  So QC is much easier for them.  Still, none of us, not even the OP, knows the prior history of the unit he received, and given the absence of any similar reports, at least that I have ever seen, on internet fora, I think you should be fair and give Technics the benefit of the doubt.  (Now even I am being a bit unfair to Technics; we really don't know what happened with this particular unit, whether it left the factory with this defect or not.)

The wobble is due to the machining on the side of the platter but the speed is consistent it may be within tolerance but it does not look good or right quality control issue i am sure.

That problem is not unique to that table that you got. Move on to another brand!

Second purchase: Second test on new Technics Sl 1200 GR. Again slight wobble.. - YouTube

I returned an SL-1200G with a platter wobble.  My SL1200MkII wobbled considerably less.
