ABSTRACT:
A needle assembly for a phonograph pickup cartridge wherein the pickup needle coupler and shank are movable relative to a drive member which is disposed between the needle shank and the mechanoelectric transducer means, to vary the position of the needle tip with respect to the cartridge drive member along the lonitudinal axis of the cartridge, and thus cause predetermined selectable changes in the needle lever ratio which in turn causes changes in compliance and output of the cartridge-needle assembly.
