I owned the FR-64 which was much lighter then 64 S. As
Dertonarm already mentioned with a round lateral weight.
I think that the arm-wand was made from aluminum which
should explain the lesser mass as well the black color.
It was a very good tracker. I got 90 microns with Ortofon
MC 30/II without any buzz from the right channel. The post
fix 'S' by the FR-64/66 means 'steel' as far as I know.
According to the German importer those are made from
'hardening steel' whatever this may mean. Anyway difficult
to produce so like the SME 1 (old steel version)
they are substituted for the aluminum kind which are easier
to produce.
