The binding posts are also mounted somewhat differently. Secure them to
the panel of the enclosure, rather than the PCB.
Then install the wires on the back of the binding posts. Run the wires
through the oblong holes in the PCB, and solder them in place.
Carefully pull the wire slack through the holes, as you slide the PCB into the
enclosure. The rotary switches will protrude through the corresponding
holes in the enclosure, and the tails of the binding posts will barely stick
through the oval holes in the PCB.
Secure the PCB in the box by mounting each rotary switch with the dress
washer and hex nut. You can use pliers or a 12mm socket to tighten the
nut.
