9 (L1 Mount the SPST on-off switch (two lugs) on

the chassis rear. The con nee tin g lugs

should be located as shown in the pictorial

diagram. No lockwashers or nuts are

necessary.

WIRING PROCEDURE

EACH LENGTH OF HOOKUP WIRE SPECIFIED

SHOULD HAVE APPROXIMATELY 1/4" OF

INSULATION STRIPPED FROM

EACH END

UNLESS OTHERWISE SP ECIFIED.

13 (---) Mount both A-470 output transformers with

#8 hardware. Note that the shorter leads

come through the holes in the rear.

(-1

Us ing 4/40 hardware, mount the seven lug

terminal strip on the left side opposite the

choke, following the pos ition shown in the

pictorial diagram.

11 ( )

Mount the choke, C-354, on the right side

below the c has sis.

Put the #8 screws

through the chassis from the top and fasten

underneath with lockwashers and nuts. The

leads should face the front of the chassis.

Connect the red-black transformer lead to

the lower

Twist the pair of white leads and dress

them from the power transformer to socket

Connect one lead to pin #2 of VI (S).

Connect the other white lead to pin

of VI.

to socket

VI.

Connect one red lead to pin

#4 of VI (S).

Connect the other red lead to

pin #6 of VI (S).

4 (?1 Twist the pair of green leads together and

dress to socket V2.

Connect one green

lead to pin 1/2 of V2.

Connect the other

green lead to pin #7 of V2.

Twist the brown pair and dress them to

socket V7.

Connect one brown lead to pin

#2 of V7.

Connect the other brown lead to

pin #7 of V7.

Connect the red -yellow lead to the solder

lug near the filter capacitor.

the red lead from the right output trans-

former through the right clamp.

Connect

both red leads to filter capacitor lug

#1.

(The lead from the right output transformer

can be trimmed to the required length).

cable clamp, con n e c t one lead to filter

capacitor lug #2 and the other lead to lug

(These leads can be trimmed as re-

qUired).

Tighten the two nuts holding the

cable clamps.

10 (v') Dress the power transformer black leads

around the end bell and connect one lead to

lug A of the fuse post (S).

Connect other

black lead to lug #l of on -off switch (S).

Connect the short black lead from the right

output transformer to lug #4 of the 4 screw

terminal strip.

Connect the brown lead to

lug #3 (S).

Connect the orange lead to lug

Mount the quadruple section filter capacitor

in the special cutout.

Fasten by twisting

each mounting tab one -quarter turn. Note

that the four connecting lugs are identified

by markings at the base of the lugs.

sure to orient the capacitor properly, with

the lugs positioned as in the pictorial.

Mount two solder lugs with a #4 screw and

nut next to the quad filter capacitor. This

is the main grounding point of the entire

amplifier and should be tightened securely

with the two lugs pointing as shown in the

pictorial.

10 (...y-Mount the power transformer, PA-060, in

the large center cutout. The wires should

face the front of the chassis.

Fasten the

two mounting screws at the rear with

lockwashers and nuts. Place a cable clamp

over each of the two front mounting screws

and fasten loosely with

118

lockwashers and

nuts.

The green, red, and white pairs of

wires should be threaded through the left

cable c

amp as should the green -yellow

and brown-yellow ones.

Pass the brown

pair through the right clamp.

MOST TRANSFORMER LEADS ARE PRE-CUT

TO THE PROPER LENGT HS AND DO NOT

REQUIRE CUTTING.

HOWEVER, THEY CAN BE

SHORTENED WHERE DESIRED.

IT IS ESSEN-

TIAL THAT THEY NOT BE CUT TOO SHORT

FOR CONNECTIONS WHEN THE

LEADS ARE

POSITIONED IN A C COR DAN C E WITH THE

PICTORIAL DIAGRAM.

IN THE EVENT THAT

THE TRANSFORMERS ARE RETURNED TO THE

FACTORY FOR REPLACEMENT

OR INSPEC-

TION, THE

LE ADS ,MUST BE OF U SAB LE

LENGT H OR THE WARRANTY WILL BE

VOIDED.
