yellow lead and the white lead to 2 1/2"
; both yellow leads to 3 1/2"
; both
red leads and both black leads to 5 1/2"
. Mount the power transformer as shown.
Position so that the green and yellow leads face the center of the chassis (see
figure 6).
Use three #8 lockwashers and three #S-32 hex nuts on three of the
screws. On the fourth screw, use one #S grounding lug and one #S-
32 hex nut.

the shield.
Under the nut without the lockwasher,
mount the cable clamp. On
the top of the chassis, mount a cable clamp under one of the screw heads. Do not tighten this screw yet. Run all leads from hole "
under the cable clamp
under the chassi~ in the direction
shown in figure S. Tighten all nuts except
the one h91ding the clamp on the top side of the
chassis.

Mount the electrolytic can capacitor,
C37, as shown. In
figure 6. note the direction of the half
moon, square and triangle near lugs to
determine direction of mounting. Insert the mounting tabs into the slots in the
chassis and twist the tabs
somewhat less than a quarter
turn. DO NOT twist
the tabs e?,cessively or they will shear off. Solder the tab without a hole to the cha~r.is at its slot.

32 hex nut. Tighten the mounting screw and nut
after the
pilot li
9~f has been lined up with the hole in the front
chassis apron.

NOTE:
Before the next step,
remove the fuseholder mounted in step 10, on
page 3C. After completing
step lIon
this. page (page 7C), remount the fuse-
holder as indicated in step 10 on
page 3C.
This time
, tighten the nut but do
not tighten too much or holder will crack.
Next, continue with step 120n this
page (page 7C), and follow the
