Dear @rossb : You can make changes in the cartridge/tonearm set up but when doing those changes we need to be aware of this:
the Löfgren equations ( for A and B alignments. ) are the foundation for alignmets as Baerwald or Stevenson.
Löfgren fixed input " numbers " for equations solution are: tonearm effective length, inner most groove and outer most groove.
From here those equations gives: linear offset, overhang, offset handle and P2S distance.
Depending which alignment type we choosed and the whole accuracy on the tonearm/TT/cartridge set up will be the tracking error and tracking distortion: before, inside and after the calculated null points.
The audiophile target is to have the distortion levels at minimum and for that we need that the set up been made it with zero tolerance.
Zero tolerance is almost imposible to have and that's why we need to take extreme care on that " accuracy " word.
In your case you can mount the AO arm at 212 ( using your F. protractor. ) if the AO/cartridge set up is amde it with the new offset angle and overhang inside the same type of alignment choosed.
When the P2S is changed what we are doing is changing the tonearm effective length and this means that depending on the P2S changes the new set up can has lower or higher tracking distortion levels inside the alignment choosed for.
So, you can mount the AO in your TT taking care of what I'm telling here.
Regards and enjoy the MUSIC NOT DISTORTIONS,
