Specialized RCA stereo cable with an additional bare ground wire (spade lug) for connecting turntables to phono preamps or phono-input AV receivers. The ground wire prevents 50/60Hz hum from ground loops that standard RCA cables cannot eliminate.

Notes & Compatibility
Most turntables have non-detachable cables — upgrading requires modification. For detachable models (Technics SL-1500C, SL-1200MK7), Mogami or Cardas upgrade cables offer lower capacitance (target under 150 pF/m for MM cartridges). Always connect the ground wire to the preamp's 'GND' terminal — without it, expect 50/60Hz hum.
