The faceplate will be secured by the washers and

ponent and insert it through the chassis and cor-
responding faceplate cut out. Reapply hardware
and tighten with adjustable wrench and pliers.
Mount your Main and Standby switches using

Mount potentiometers using their pre-assembled
hardware and 1/2” nut driver. Make sure poten-
tiometers are mounted with their lugs facing up
towards the open end of the chassis.
PRO Tip: When mounting the pots, make sure the
toothed locking washer goes between the potenti-
ometer and the chassis. The at washer will go on
the outside of the chassis and the nut will tighten
down.
Once you have the pots securely installed, turn the
shaft of the pot all the way counter-clockwise. In-
stall the knob on each pot, making sure the point-
er of the knob is pointing to “0” on the faceplate.

set screw, back the knob off of the pot 1/16‘‘ and
re-tighten.
