Fidelity Research FR-64x

@chakster , Your Lustre 801 has only the (thin) armwand

made from steel. The same apply for the SME ''R'' kinds.

The effective mass by FR-66/64 S depends from the used

headshell and counterweight. I never used any of the FR

headshells because I consider them all as worthless.

For the FR 66/64 series 3 different counterweights are made:

standard, 170 g and 250 g. One should use the weight which

can be moved nearest to the pivot. The least inertia is the

result. The worst headshell is S3 ( 19,5 g). The other are to

short for the usual headshell wire length. So the effective length

is not easy to adjust (stylus ''distance'' to the pivot). I prefer

headshells made from magnesium with ''movable 4 pin connector''.

This kind make azimuth adjustment possible as well the added

space for the stylus adjustment.

 I bought the Pink Triangle for $150 locally in Hicksville LI back in the days when you could find stuff in Newsday classifieds almost everyday.
The guy I bought it from kept his arm but hooked
me up to another guy for the Fidelity Research, for another $150
