When making connections to the speaker terminal PWBs, support the board as needed to avoid
stressing the PWB.
– Using two tie-wraps, bundle the wires running along the back panel where the right
channel speaker PWB will be mounted. Position the wire bundle about 1/2-inch away
from the back panel.
– Insert the right channel speaker PWB over the right channel barrier strip posts. Orient the
board so the relay faces the center of the chassis.
– While holding the board in position, solder the two speaker barrier strip terminals to the
right channel speaker PWB.
– Insert the 4-pin Molex connector from output transformer T1 into the Conn6 post. The
black lead goes to pin #1.

speaker PWB will be mounted. Position the wire bundle about 1/2-inch away from the
back panel.
– Insert the left channel speaker PWB over the left channel barrier strip posts. Orient the
board so the relay faces the center of the chassis.
