– Mount the two RCA input jacks using the #4 hardware provided. Orient the components
so the ground lug faces downward toward the chassis bottom plate.
– Mount the ground lug terminal. Place the four ground lugs on to the 3/4-inch long #6
screw provided. Using a pair of long-nose pliers, bend the ends of the lug upward (toward
the head of the screw). Insert the screw into the back panel hole so the screw protrudes out
of the back chassis. Install a lockwasher on the screw, and then the lock-tight nut. Spread
the ground lugs on the inside of the chassis so they can be used individually. Tighten the
lock-tight nut. Install two flat washers on the screw and then the wing nut. Tighten the
wing nut finger-tight. The finished installation is shown in Figure 5.9.
– Install circuit breaker CB51 using the hardware provided. Position the device so the
number rating is properly oriented when viewed from the rear. Run the decorative nut
down so it is flush with the mounting shaft. Use the chassis-side nut to tighten the
component in place.
– Mount the speaker output terminal strips, TG1 and TB2. Install the right channel terminal
strip and secure with the #4 hardware provided. Repeat for the left channel terminal strip.
Make sure that the mounting screws do not extend beyond the #4 nut. Trim the screw
length as needed.
