Halcro - I have to agree with Raul, your numbers dont add up.

The MA-505s was no problem because it's overhang is the same as the FR-66s.....however the FR-64s has an overhang of 12mm as opposed to the 15mm for the others.
So to correct for that......I reset my P to S to 233mm for the 64s.
And yes......I know that the Av and Max distortion levels go up as a result.
The FR66 should be 12mm overhang not 15. The FR64 should be 15, not 12.
If you are running 12mm overhang on your FR64 then you should be moving the arm closer to the spindle to reduce distortion, not further away.
