The wire from C7 LEFT - terminal to
LEFT PC-14 eyelet 11.

The wire from the LEFT input socket to
LEFT PC-14 pin 12 (typically a green
wire).
7
The wire from the LEFT input socket
ground to LEFT PC-14 pin 13 (this is
typically a black wire).
8
The wire from LEFT Q6 E terminal to
LEFT Speaker ground terminal.
You may not be able to reach your cutters to LEFT Q6 E terminal. Don't worry. We'll
make it easier now, while we check your work to this point. With the exception of this
one wire, the LEFT power amplifier module is free to lift out as soon as you remove the
two #6 screws that hold the LEFT heat sink to the chassis. Unscrew the screws, lift out
the module, and cut the wire that you couldn't reach in the previous step.
Save the LEFT module and mounting hardware. We will re-use the heat-sink and some
other bits as described in "Salvaging the heat sinks from the amplifier modules".
