Technics SL-1300G Turntable issues

@faustuss 

Sorry you don't understand the fact that the platter is the part that really needs to be leveled. Of course you start with the base but if the platter is not leveled after leveling the base, you need to adjust the feet until you get the platter leveled.

On a quality TT like my VPI Classic the level of the base is identical to the one of the platter. But on lesser quality TTs like the Pioneer DX1000, or Pro-ject debut, I had to make legs adjustments to get the platter leveled. 

Luckily the VPI Classic can handle heavy center weight and outer ring. I use them for every record I play so they are pretty flat. If you truly want hifi results, this vinyl thing can be tedious. Tone arms / cartridges alignments and specially the cleaning vinyl and storing  part. Not for everyone. 

I just checked your system and you seem totally committed to vinyl. It is very easy to check a platter for proper level. Just use an eye bubble type level and move it around the platter and check that the bubble stays dead center in the eye. Then move your platter to multiple positions and repeat the bubble test. Once you have made a 360 platter revolution and all positions had the bubble centered, you know your platter if leveled and spinning without wobble. However that was not the OP's concern. His concern is over the side of the platter having lines that are not uniform as platter turns. Anyway that was my understanding.

Guys, please read the OP's post before going on about checking the platter being level, he states it is. His complaint is that the cosmetic silver bands at the top and bottom of the outer sloping rim, vary in width. This is a variation of the manufacturing process. The platter is a high pressure die casting, which has the centre hole bored and then the platter is centred on this to true up the casting an a lathe. The silver edges can vary due to this truing up process. (The difference between as cast and machined around the centre hole).
That's all it is.
The OP has to decide if this purely cosmetic variation is something he can live with, or if he requires a different platter that has more equal lines.

As for the modern Technics being substantially better, I would disagree. They are very slightly better, a little mass has been added to the platter and the bearing has been slightly improved, but that's about it. The marketing bull about the new motor being better is just that. I run a DIY turntable using the DD drive motor from an old SL-1200 MkII, if you check the wow and flutter figure, its the same as the SL-1300G (0.025%). You could argue extra torque, but is that needed or audible? My motor runs a heavy 38mm thick acrylic platter and stops and starts on a dime.
They are and always were, a very accurate and stable platform for your records.
