Dear Henry, As Raul stated I assume that we all want to learn. The first review about the FR-64s that I have read was the German Magazine 'Das Ohr' (the ear) from 1984. Our
member Dertonarm was then a reviewer by this Magazine. Regarding the tonearm geometry already than both reviewers made the remark that the geometry in the user manual was not optimal. They recommended the spindle -pivot distance of 231,5 mm instead of 230 mm in the manual. With 'optimal' geometry they meant the Bearwald. Well I recently ordered by Yip his Mint protractor for my FR-64- SP 10 combo. Yip wrote to me that the geometry in the user manual is Stevenson : 230/ 244,9 ( spindle -pivot/ eff. lenght).
For my combo I wanted Bearwald which according to Yip imply :231,5/ 248,2 mm respectively. I am not sure if you referred to your FR -66 or 64 with your statement that the geometry of your FR tonearm and FR-7 cart is 'perfect' Bearwald but if you referred to your FR-64 this can't be true. I never owned the FR-66 so I have no idea which geometry is assumed in the user manual for this tonearm. But I am familiar with the FR-64 from 1983 till now.
I agree with Raul reg. the integrated headshell/carts combos's but my reasons are more pragmatic than theoretical.
Regards,
