Abstract: A rigorous proof is given of the new analytic formula recently presented by Jovanovic for the linear offset p in Löfgren C alignment. An alternate but mathematically equivalent form of this formula shows explicitly that p depends weakly on 1/L 2, where L is the effective length of the tonearm. Simplified derivations of several results for Löfgren A are also presented. Approximate formulas for Löfgren C valid in the limit of large L are derived, compared with accurate numerical calculations, and shown to be sufficiently accurate to account qualitatively for the optimum values of the tonearm parameters over a wide range of L.
