Abstract
A pick-up phono cartridge in which the position of an armature disposed at a base end of a cantilever is made adjustable to thereby produce a desired output voltage. A vibrating system of the cartridge includes an armature secured to a base end of a cantilever having a stylus secured to the other end thereof. A center axis of the cantilever is vibratable around a predetermined position on the armature. A fixed system is provided including at least a front yoke and a rear yoke which are positioned to nearly clamp the armature. The vibrating system is made adjustable in the axial direction of the cantilever upon loosening a stop screw.
