RE: Fidelity Research FR64S

I guess it depends on what you mean by "Baerwald alignment". The effective length of the FR-64S tonearm is stated to be 245-mm. Therefore, if "Baerwald" means that you're referring to alignment null-points of 66-mm and 121-mm, then you really need to increase overhang from 15-mm to just under 17-mm. This would yield a pivot-to-spindle mounting distance of just over 228-mm rather than 231.5-mm.

Use the equation below: Mounting Distance = D = Sqrt(2452 - 66 x 121) = 228.12-mm

Good luck,
