technics 1200g tonearm question headshell angled not parallel to lp

What does listing inwards mean? If you explained properly, maybe we could help.

its tilted toward the platter side of the table

Up til now, I thought you were saying that the headshell does not sit at zero degrees azimuth, which means that when you view the headshell "on end", the flat top surface of the headshell is not parallel to the LP surface.  If this is NOT what you are worried about, then what ARE you worried about?  And before you go further, keep in mind that it is not a given fact that all headshells fit all tonearms properly.  I have seen some gross mismatches where the aftermarket headshell won't firmly seat in the end of the arm wand. Which is why you are best off to start out with the OEM headshell and work from there.

I disagree with Invictus, there should NOT be any play between the headshell and the arm wand when the collar is tightened.  And as you tighten the collar, play or wiggle in the azimuth setting should become increasingly limited until there is none.  At that point, if you perceive a need, you can use the built-in adjustment for azimuth on the headshell itself, if that is available.

@lewm I never once said there should be any play with the collar tightened. But there should be enough play with the collar loosened a bit, enough to adjust azimuth properly. I own the 1200G and everything adjusts perfectly. Never seen any azimuth issues on any other 1200s either.

Obviously OP refuses to take the time to properly explain the issue, so I’ll no longer waste my time trying to figure out his problem.

Invictus, Sorry for misunderstanding the intent of your post.  I agree with you that the OP seems to have left the building.  In cases where the headshell and arm wand are mis-mated, I HAVE seen some "wiggle", even after the collar is as tight as it can get.  That to me means the headshell and the tonearm do not like each other.
