FINISHING PC BOARD ASSEMBLY
Cut three 3” pieces of wire from the roll of 22 gauge solid wire and strip 1/4” of insulation off of each end. Using
these wires, solder the 5kΩ potentiometer (VR2) to the PC board and put a check mark in the box (!) after all
of the wires are in place. This part should be similar to the sketch shown in the box, but may differ in size. Be
sure to mechanically each wire as shown in the figure below before soldering.
