Hexagonal spanner for Fidelity Research FR 66S tonearm

Am hoping to sell for a friend but can not remove the piece from the arm board. Manual mentions a hexagonal spanner. Does not seem to be included in box nor could I find a pic to possibly jog owners memory. Anyone out there who can help? TIA, LS

I have an FR64S but I don’t think the fixing nut is hexagonal. I’ll check later today. Meantime you could measure the nut with a caliper and just buy a suitable “spanner”. Because of space limitations under an armboard, I think a socket wrench would work better.

Thanks, I have been able to remove armboard so space may not be an issue.

So sorry. I just tried to gauge the size of the hexagonal nut that does fix my FR64S to the armboard, and I can barely see it without dismantling it, which I am loathe to do. The only thing I can say is that it IS hexagonal, as you say, But if you've got your armboard off the TT, then you will have no trouble determining the size of the nut. It's probably metric and seems to be at least 27mm.

Pani,
in the case of the FR-66s you may neglect the compliance issue. We made many tests with nearly all available MC carts, MI carts and new as well older MM designs on the FR-66s. No problem at all. It is the most universal arm ever built."

from this discussion of the 66S here

I apologize ahead of time for the bald spot you might make scratching your head trying to ascertain what's 'best'.
