Tools

  • Phillips Head Screwdriver: Size PH1
  1. 1

    Step 1

    • Unplug the turntable from power and speakers, then place it on a flat level surface
    • The turntable will be flipped upside-down, to reduce the risk of scratches to the acrylic dust cover, place it on a soft surface such as a blanket, towel, or sheet
    • Using a twist tie, tape, or ziptie, secure the tonearm in place so it won't move after being turned upside-down (do not rely on the tonearm hook alone)
    • Remove the rubber slipmat, belt and platter from the center spindle
  2. 2

    Step 2

    • Make sure there is something soft underneath the dust cover like a bedsheet, towel, etc to minimize the risk of scratches to the acryllic
    • Flip the turntable upside-down
    • Remove 6 Phillips head screws to remove the metal PCB cover
  3. 3

    Step 3

    • Remove the screw for the ground wire
    • Remove the 4 screws holding the Center Base Assembly in place
    • Gently unplug the 4-pin connector of the Center Base Assembly
    • Remove the Center Base Assembly
    • This is the end of the guide, to reassemble, follow the steps in reverse
    • When fastening the metal PCB cover, make sure all wires are within their channels or the cover might flatten/damage the cable
