Bend Tab Over
Bend the mounting tab on the pot over. Place a 5/16" lockwasher onto the
shaft of the pot. Insert the shaft of the pot into the hole in the PC board from
the copper side. Position the pot so that the three lugs are above the three
copper pads on the PC board. Secure the pot to the PC board with the 7mm
pot nut and 8mm flat washer. Solder a bare wire (discarded resistor lead)
from the pot lug to the pad directly below on all three lugs.
