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
- Pull directly upward on the speed selector knob to remove it
