Remove the stainless steel, flat head, slotted screws (<1g) holding the potentiometer knob (23.1g) we saw in Step 10 using a flat-head screwdriver.

Once screws are removed, the knob is easily pushed through the holes in the frame and pulled out of position. However, it is still connected to all the sets of wires soldered onto it.

Using a pair of plier, I ripped the soldered wires off one by one. This was very difficult and required many attempts and tight clenching of the pliers, twisting and rotating them at various angles to weaken the bond, often ending up removing the small soldered platforms for each wire too.
