    • Unlock the four rubber feet by turning them 90° counterclockwise using your thumb or finger tip.

    • There is a tiny mark on every foot facing the bottom edge of the OP-Z. After turning them they should face towards the short edge where the on/off switch is.

    • When turning the OP-Z over again the bottom plate should come off by itself (thanks gravity).

    • If the bottom plate won’t come off you might want to make sure every foot is rotated correctly and gently tug on one of them.

  3. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 3, image 1 of 1
    • Remove the bottom plate including the rubber feet.

    • Use your finger or a spudger to push up on the small tab on the bottom of the module.

    • Lift the module up and out of its recess bottom first.

  7. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 7, image 1 of 1
    • Remove the module.

    • When inserting another module make sure you put it in outputs first. Then push down the bottom part for the tab to engage.

    • Place a spudger in the cutout of the extension module to lift the midframe.

    • Be careful not to damage the highway flex cable underneath.

    • Don’t remove the midframe yet. It is still connected to the rest of the OP-Z.

    • Slowly pry the USB-C connector out of its recess. Use the flat end of a spudger on the small nib on the USB-C board.

    • The connector is slightly glued down.

  15. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 15, image 1 of 3 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 15, image 2 of 3 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 15, image 3 of 3
    • Insert the pointy end of the spudger into the line-out jack and lever it up carefully.

    • The jack connector might sit tight and is slightly glued down.

  16. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 16, image 1 of 3 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 16, image 2 of 3 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 16, image 3 of 3
    • The highway flex cable is slightly adhered to the midframe. To remove it, gently push it out from underneath.

    • A small transparent part may pop out. This is the light guide for the bluetooth indicator. Just hinge it back onto the midframe as seen here.

  17. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 17, image 1 of 3 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 17, image 2 of 3 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 17, image 3 of 3
    • Peel the highway flex cable off the midframe and remove it.

    • Use one arm of a tweezer to lift the small black flap of the ZIF connector.

  19. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 19, image 1 of 2 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 19, image 2 of 2
    • Use a pair of flat nose tweezers to pull the small flex cable up and out out the ZIF connector.

    • When reassembling make sure to insert the flex cable all the way.

  20. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 20, image 1 of 2 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 20, image 2 of 2
    • Grab the volume knob with your fingers or a pair of pliers and pull it off its axle.

  21. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 21, image 1 of 2 Teenage Engineering OP-Z Volume Potentiometer Replacement: step 21, image 2 of 2
    • Use a spudger to lever up the axle of the volume potentiometer. This way it will clear the frame’s cutout.

    • The volume pot is slightly glued down.

  22. Teenage Engineering OP-Z Volume Potentiometer Replacement: step 22, image 1 of 1
    • Remove the volume potentiometer.

Conclusion

To reassemble your device, follow these instructions in reverse order.
