I'm running an Shure M-80 and Shure pre-amp in a 1965 Wurlitzer stereo jukebox, replacing the Sonotone ceramic original (yechh). Great sound, but the arm needs the 4-5 grams tracking capability of the M35S (or SC35C).
The SC35C is a standard mount: two holes in the cartridge; 1/2" apart; screws pass through the holes and into the headshell. The M35S is the same mounting.
SC35C width: 5/8"
SC35C length, including the pins: 1 1/16"
SC35C height: 5/8"
The M35S has the same dimensions.
