@nkj nice, i wish i could add that B-60 base and N-60 stabilizer to 64s.
The 64fx is good as it is, in its stock condition.

I use Stevenson geometry with my FR-64fx + FR-7fz cartridge, as recommended by the manufacturer (Ikeda San). With this cartridge you can not change the geometry as you simply can’t twist the cartridge in the "headshell". With conventionel cartridge you can change the geometry, but not with a headshell integrated FR-7 series.

Dear chakster, In my FR manual only the small FR-64S (170g)

and heavy FR-64 fx (250g) are mentioned. I own, next to 170g,

also 250 g weight for my FR-64S. The later is according to me

the standard weight. I never needed heavier kind. But do use

the 170 g for light cartridges. I mean MC kinds in my case but

this should also apply for the most MM carts.

@chakster looking forward to your sonic comparison between both arms! I do agree with your description of the built quality and operability of the 64fx. Definitely not 'a poor man's 64s'.....

@nandric 

Could you measure your counterweight ?
The one i have with my 64s is 25mm long (side measurement) and this is definitely not the smallest one. 

Dear chakster, You obviously got the original : 25 mm long and 250

g. weight. Like by B-60 there are also replica weights. The original

has an rubber ring inside and screw with plastic piece with a spring

on its ''nose''.
