has. Pull the stop up and move it to a higher (or lower) position. Replace the nut and knob and
recheck.
After the switch position stop has been properly set, remove the knob and observe the body of
the switch. There is mounting tab on one side of the body. Using a pair of wire cutters, remove the
tab.
Bend the tabs on the switch back toward the rear of the device to approximately a 45-degree
angle. This will facilitate connection of the terminals later in the process.
– Place a flat washer on the shaft of SW101. Mount the switch in the Input position on the
front panel using a lockwasher and nut. The nut should be finger-tight for now.
– Mount the power switch (SW51) to the front panel as follows. Unscrew the push-button
from the device. Remove the mounting nut from the shaft of the switch. Leave the fiber
washer and lockwasher in place. Mount the switch to the chassis/panel and secure using
the nut provided. Do not tighten. Note the connection terminals on the switch. The center
screw terminal should face downward toward the chassis bottom plate.
– Mount pilot lamp PL51 as follows. Thread the large mounting nut on the pilot lamp and
run down to the base of the threads. Place the lockwasher provided on the shaft. Mount the
pilot lamp to the chassis/panel and secure with the decorative nut provided. Run the
decorative nut down to be approximately flush with the mounting shaft. From the
underside of the chassis, spin the large mounting nut up toward the chassis and tighten.
– Using caution to not scratch the finish, tighten the front panel potentiometer mounting
nuts. Check to make sure the terminals of the potentiometers are facing downward toward
the chassis bottom plate. When tightening the nuts, do not use excessive force as this may
strip the threads and leave the component unusable. This is particularly important on the
Bass and Treble devices (R127 and R132).
– Using caution to not scratch the finish, tighten the headphone jack nut. It is often best to
tighten the jacks by holding the mounting nut steady and turning the body of the device
from the chassis side. This will reduce the possibility of scratching the font panel finish.
The keyed side of the 1/4-inch jack should face downward toward the bottom of the
chassis.
