Desolder the wire connected to the RED terminal of C7L.
3.
Desolder the wire connected to the BLACK terminal of C7L. Pull off the big
hanging coil of wire. It will not be re-used. Locate the other side of that coil of
wire where it connects to the front panel speaker switch. Cut that wire near the
speaker switch, but be careful not to cut the green wire on the switch which is also
connected to the same switch terminal.

Cut and mark the following wires close to the eyelets on the power amp PCBs:
c.
Eyelet 12 of right channel (front-most) power amp PCB, and label it
“RIGHTIN”.
d.
Eyelet 12 of left channel (rear-most) power amp PCB, and label it
“LEFTIN”.
e.
Eyelet 11 of left channel (rear-most) power amp PCB, and label it
“INGND”.
7.
Cut and remove the following ground wires at both ends:
f.
Eyelet 9 of left channel (rear-most) power amp PCB, and its attachment to
the ground of C11.
g.
Eyelet 9 of right channel (front-most) power amp PCB, and its attachment
to the ground of C11.
h.
Eyelet 11 of right channel (front-most) power amp PCB, and its
attachment to the ground of C11.
9.
Identify the wire that connects to eyelet 10 of the front-most power amplifier
channel. Clip that wire where it connects to C11, near C11.
10.
Identify the wire that connects to eyelet 10 of the rear-most power amplifier
channel. Clip that wire where it connects to C11, near C11.
