On the soldering side of some boards, you need to put down some additional wires or trimpots
The wires are indicated by grey curvy lines on the soldering side (e.g. the phaseur needs 8 or so). Just cut a piece of wire the right length, strip the ends 1/16” inch, and solder it onto the twisted wire joints.
For trimpots, solder two of the leads (the center one and one other) directly to the two twisted wire joints on the solder-side. Make sure it won’t wiggle around.
