Dover,
Stevenson - 60.325, 117.42mm
Baerwald - 66.0, 117.42mm
Loefgren(B) - 70.3, 116.6mm
Dynavector - 60.1, 116.5 Notice anything unusual?
Alignment is defined by a standard, not a test record. Inner null is standard lead-out groove. Even if you use IEC (or whatever it is) the numbers are very close and the relationship between inner and outer null is the same, only moved slightly, just as UNI nulls are Loefgren B moved in 5mm, with a variance of 0.1mm.between the nulls.
It seems to me, the suggestion to align to Stevenson is ill conceived. Further demands to change to one of the Loefgren alignments by changing mounting distance, is bizarre.
I've already posted this information and I have to agree with Lewm, life is too short.
Regards,
