A tone arm for sound reproducing apparatus comprises an elongated member of electrical insulating material arranged to support a pick-up head at one end and to be pivotally supported at a point remote from said one end. Several spaced electrical current conductors are carried by the elongated member. The electrical current conductors are formed by a printed circuit technique. At least selected conductors are arranged to be connected at one end to a pick-up head mounted on the arm and at the other end to take-off leads.
