Technics SL-1300G Turntable issues

@dmorse6736 Awesome! Maybe you need to think about going a little upmarket. Honestly, the only higher end turntables I've lived with are my previous Rega Planar 8 and Apheta 2 and 3 combos (which is excellent by the way especially for the price with great resale value.) and my Luxman PD151 MKII and Hana ML. I don't know what your budget is but these days the Planar 8 sells for $5000 with an Apheta and the Luxman $6500 with a cover which you would definitely want. The arm on the Luxman has all the requisite adjustments you would need for your Umami and will accommodate medium to high medium mass cartridges and you can also purchase an optional counterweight for heavier cartridges.

If you don't use one already, I recommend a good test LP. I use the latest version of the Hi-Fi News LP which comes with a Stevenson protractor. I also use and alignment block for VTA and azimuth and there is a track on the test LP that cleverly uses a null to verify your azimuth setting provided you have a mono button somewhere in the chain, plus, a spirit level and good stylus force gauge.

I may just be spinning my wheels since I'm sure you're up to speed on all of this but I hope I've been helpful.

@faustuss my system includes a DIY Preamp based on the 6922 Tube, DIY Monoblock amps using KT88,   Hana Umami Blue cartridge,  musical fidelity phono stage,  TT TBD and Klipsch Cornwall speakers.  Pioneer Elite CVD/CD for digital media.   Some room treatments and premium cables.   
 

My theatre has a VPI Scout TT with a HANA ML MC catrridge (TT soon to be TBD)  Musical Fidelity phono stage,  Yamaha Aventage 2000 used as PRE/PRO.  OPPO 205 for digital media.  DIY monoblock amps using KT88.  Klipsch in wall speakers for movies.  Belle Klipsch with Klipsch subwoofer for 2 channel and movies.  DLP projector, 10’ screen.  The room is heavily treated with Rt60 at less than 250ms.

 

Perhaps not surprising, but I am experiencing a similar issue.

Brand-new Technics SL-1300G installed as per instructions (followed meticulously). I ensured the screws, washers etc were installed 100% correctly. Only to find a ~1mm spacing variance on the platter itself. The platter is placed perfectly level.

Now it might sound negligible, but when the platter spins, it actually causes a vertical displacement, causing the record to move up and down on the platter itself. Perhaps it doesn't cause any audible effect (who knows?), but nonetheless highly disappointed. 

Perhaps you should take a short video of it and send it to the manufacturer and ask for their comment.  That is what I would do.

1bitsoul, your problem is quite different from that of the OP, because his complaint is only about lines on the edge of the platter not being of uniform thickness. Someone else suggested this is only a functionally harmless result of its machining. What you’ve got is not hatmless (platter wobble), and you ought to complain to the seller. You need a replacement.

I was looking at getting a Technics table but posts like this and others about the quality of the cue mechanism made me look at other brands. 

I ended up buying a Sota Escape open box for $1799.  Sapphire bearing and the excellent Condor motor and controller.    Came with upgraded 1.5" platter and Origin Live Silver arm.    Made in USA / UK   , not Malaysia
