) Strip and tin both ends of an 18' length of
.Z-conductor line cord.

) On one and connect one lead to lug 1 of the
VOLUME control switch AU (S-l). Connect
the other lead to lug 2 of the VOLUME
control switch AU (S-l). See Figure 23.
Form the other end of this pair over the
chassis between the front end assembly and

0/ circuit board, as shown in Figure 26.

)

Prepare the length of shielded cable as
shown in Detail 1?. Tin the shield pigtails
and the center conductor.

) Refer to Figure 23 and place the end with
1-1/2' of outer insulation removed through
hole BE from the top of the circuit board.
Run the center conductor lead through lug 2
of the phone jack AF and pull the lead
through to the point where the end of the
outer cable insulation is flush with the
top of the board (but not under tension).
Make connection and solder lug 2 (5-1).
Connect the cable shield lead to lug l
of phone jack AF (S-l).

Connect one end of a 1-1/2' length of yel-
low hookup wire to lug 3 of the phone jack
°AF (S-l). Connect the other end of this
lead to the speaker terminal pin (S-l).
See Figure 23.
