When connecting wires to the PC-9 circuit board note that
the eyelets on this board are numbered in the reverse direc-
tion from the lug numbers on the terminal strip.

Strip a
1-1/2“length
of heavy wire bare. Connect one
end to large capacitor CL lug X2. (S). Connect the
other end to CR lug #3. (S). Be very
sure
that these
connections are well soldered because they will
carry considerable current.

Select one of the spade lugs. Connect it to the other
end of the green wire just attached to lug #3. (S).
The proper way to connect one of the spade lugs to
the wire is to bend the shorter, wider set of tabs
tightly around the bare wire, and bend the outer,
longer set of tabs around the insulation. Then flow
solder into the joint around the bare wire.

Place the red, black and yellow wires toward the
left and twist them lightly together. Keep these
against the chassis and connect the red wire to dual
fuse clip FR lug #5. Connect the yellow wire to FR
lug #6. Connect the black wire to the center of the
bare wire between the two capacitors CL and CR.
(S). Six other wires will be connected to the center
of this bare wire. The amplifier will have the lowest
hum if the last wire to be connected (from the
transformer
-a heavy wire) is placed in the exact
center of this link between the two capacitors, so
leave a small space for it. However, all 7 wires
should be connected as near to the center point as
possible.

Prepare a 13” white wire. Connect one end to the
lower hole of
LT
lug #6. (S). Using the lower hole
will make it easier for other wires to be connected
to the same lug.
NOTE
FOR MULTIVOLTAGE
OPTION
:
This wire may need
to be 1” longer, and may connect to another termi-
nal for some line voltages.
