Fidelity Research FR-64x

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.

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''.
