Dear @dover : FR as Technics and other vintage japanese tonearm designs took Stevenson alignment as their sample alignment and seems to me that all of them did not matters to much ( in those times. ) about accuracy critical importance on the alignment set up parameters but FR took Stevenson too:
The FR66 specs says: 16.8° as offset angle and ST is 16.84° and for the overhang FR says 12mm and ST 11.8. If you make the calculations for the FR 64 is more or less the same.
FR choosed by ignorance Stevenson. The Ikeda IT-407and 345 are the same as the FR tonearms.
From where came/comes your statement that they don't took as sample Stevenson alignment?
AZ: ther FR headshell integrated cartridges has not an azymuth mechanism to change it when it needs.
