13( ) Prepare a 3 1/2" (9 cm) yellow wire, and connect one
end to MS lug #5 (S). The other end will be con-
nected later.
14( ) Select the black wire from hole G1, and connect it
to MS lug #1 (S).
Turn the amplifier over, positioned as shown in the Pic-
torial Diagram. You will now connect wires to the remain-
ing numbered holes on PC-44. Each wire is connected and
soldered from the foil pathway side of the board—the side
toward you.
15( ) Prepare a 3 3/4" (9.5 cm) black wire, and connect
one end to hole #6 (S). Position this wire to the left
along the back edge of PC-44, and connect the
other end to T-5 lug #9 at the tip (S).

16( ) Prepare a 4
/
(11 cm) black wire, and connect
2
one end to hole #2 (S). Position this wire along the
left edge, around the board, and connect the other
end to C1 lug"D" (S-2).
17( ) Prepare a 3 1/2" (9 cm) black wire, and connect
one end to hole #12 (S). Connect the other end to
C1 lug #1 (S). Position this wire around the right
edge of the board.
18( ) Prepare a 2 3/4" (7 cm) black wire, and connect
one end to hole #11 (S). Connect the other end to
C1 lug #2 (S-3). Position this wire at least
cm) to the left of hole #10.
19( ) Prepare a 2 1/4" (6 cm) black wire, and connect one
end to hole #9 (S). Connect the other end to T-4
lug #4 at the tip (S-2).
20( ) Prepare a 7 1/4" (18.5 cm) black wire, and connect
one end to hole #5 (S). Position this wire along the
left edge of the board, and connect the other end to
T-2 lug #3 at the tip (S-3).
21( ) Prepare two 4
" (11.5 cm) black wires. Start with
1/2
the wires even, and twist them uniformly together
to within V2" (1.3 cm) of the other ends of the wires.
Connect one end of one wire to hole #8 (S), and
the corresponding end of the other wire to hole #7
(S). Connect either wire at the free end to TD-1
pin #1 (S-2). Connect the remaining end to TD-1
pin #6 (S-2). These twisted wires should be arched
in the air, away from PC-44, until they connect at
their respective ends.
22( ) Prepare a 5 1/4" (13.5 cm) black wire, and connect
one end to hole #10 (S). Connect the other end to
V3 pin #6 (S-3). This wire, as well as the black
wire connected between V3 pin #6 and V2 pin #6,
should be arched in the air, away from other com-
ponents and wires, until they connect at their
respective ends.
23( ) Prepare another 5 1/4" (13.5 cm) black wire, and
connect one end to hole #1 (S). Connect the other
end to V4 pin #6 (S-3). This wire, as well as the
black wire connected between V4 pin #6 and V5
pin #6, should be arched in the air, away from
other components and wires. Note, however, that the
shielded cable connected to the input sockets may
come in contact with the black wire connected be-
tween V4 pin #6 and V5 pin #6.

24( ) Select the line cord and the strain relief. Mark the
cord 112 1/2" (32 cm) from the stripped wire ends.
Bend the cord sharply back on itself at the mark-
ing so that a "V" is formed. See the accompanying
sketch. Install the strain relief through the remain-
ing hole in the left back corner of the chassis. The
small end of the strain relief faces the stripped end
of the wire. With heavy pliers, crimp the two halves
of the strain relief together around the wire to par-
tially shape the wire before insertion. Now grasp
the larger diameter portion of the strain relief with
the tips of the pliers, squeeze it fully closed, and
insert the combination from the outside. The strain
relief snaps into its locked position when fully
inserted.

1/2
25( ) Separate the two conductors of the line cord from
the stripped end to the strain relief, and cut off 9 1/2"
(24 cm) from one (either) conductor. Strip about
3/8" (1 cm) of insulation from the short-cut con-
ductor, and connect it to power fuse holder lug #2
(S). Position the other (long) conductor against
the chassis on the left side. This conductor will be
connected later.
Before attaching the front panel assembly in the next
step, you should check carefully for any insecure connec-
tions, and for any possibility of bare wires contacting other
than the intended terminal.
Leave the amplifier upside down, as shown in the Pic-
torial Diagram, but position it so that the front edges of
both transformers are slightly over the edge of your work
surface.
1( ) Select the front panel assembly, and two 1/2" #10
black screws with large (truss) heads. Support the
panel in front of the amplifier near its final loca-
tion (the panel will be upside down). See that the
speaker fuse and the power switch on the front panel
pass through their respective openings in the chassis.
Now attach the panel loosely on the front of the
chassis with the screws inserted from the front. No
other hardware is required, since the chassis is sup-
plied with threaded nuts.
You will now connect the free ends of the wires from
underside the chassis to parts on the front panel.
2( ) Select the yellow wire from C1 lug "C", and connect
the free end to speaker fuse holder lug #2 (S).
3( ) Select the yellow wire from output strip #1, and con-
nect the free end to speaker fuse holder lug #1 (S).
