Improved lead wires for use with a stereo record playback system where at least a pair of left channel wires and at least a pair of right channel wires extend from a pick-up device through a tone arm to a stereo amplifier, the lead wires including a ground wire and the left and right channel wires, the ground wire being disposed between the left channel wires and the right channel wires to provide electrical isolation therebetween and the ground wire and left and right channel wires being bonded together as a single unit so that the electrical isolation is implemented within the tone arm without the addition of undue weight to the arm. The right channel wires may be twisted together as may the left channel wires. The ground wire and left and right ground wires may all be separated and unbonded from one another at least at the area of the pivot of the tone arm to facilitate rotation thereof.
