WIRING INSTRUCTIONS

Connect one of the black power transfor-

mer leads to lug #2 of the slide switch

(8).

Connect the other black lead to lug

of the fuse post

(8).

Connect one yellow power transformer

lead to pin #2 of socket V 1

(8).

Con-

nect the other yellow lead to pin #8 of

socket VI.

the hole near the four screw terminal

strip. Use #8 hardware to secure the

transformer.

Mount the quadruple section filter ca-

pacitor in the special cutout. Observe the

symbols at the base of each connecting

lug. These should be oriented as shown

in the pictorial. Fasten the capacitor by

giving each of the mounting lugs a quar-

ter turn while holding the capacitor

snugly against the chassis.

Twist the two red leads together and

position them around socket VI. Con-

nect one red lead

pin #4

(8).

Con-

nect the other red lead to pin #6 of

(8).

Twist the two green power transformer

leads together and position them to

socket V2. 8EE PICTORIAL. Connect

one green lead to pin #2 of socket V2,

and the other green lead to pin #7 of V2.

Connect the green/yellow lead to lug #2

of the five lug terminal strip.

Connect the red/yellow lead to solder

lug at the mounting screw of the five

lug strip,

Connect the red/black lead to lug #4 of

the five lug strip.

Connect one choke lead to Jug #1 (semi-

circle) of the quad filter capacitor. Con-

nect the other choke lead to lug #2 of

the filter capacitor.

Connect the black lead of the A-470

output transformer to lug #

of the four

screw terminal strip. Connect the brown

lead to lug #2 (8). Connect the orange

lead to lug #3 (8). Connect the yellow

lead to lug #4.

Connect the red output transformer lead

to lug #2 of the filter capacitor. Twist

the remaining leads together and carry

them

sockets V2 and V3. 8EE PIC-

TORIAL. Connect the blue/white lead

to pi n #3 of socket V2 (8). Connect the

green/white lead

lug #4 of socket V2

of insulation 'stripped from each

end unless otherwise specified. Transformer leads

may be trimmed as required for a neat wiring job.

MECHANICAL ASSEMBLY

Pictorial Diagrams for Location of Parts

Mount the four octal sockets with #4

screws, nuts, and lockwashers (the small-

est screws supplied). Note that there is

a small slot or keyway in the center hole

of each socket; be sure in each instance

that this keyway is properly oriented as

shown in the pictorial diagrams. Insert

the screws from the top of the chassis and

mount the sockets from the inside. Fasten

each screw with a nut and lockwasher.

Mount the input socket from the inside

of the chassis using #4 screws, nuts, and

lockwashers.

Using #4 hardware, mount the four screw

terminal strip on the outside of the

chassis.

Mount the slide switch from the inside

with #4 screws. Nuts and lockwashers

are not necessary in this instance. Follow

the position of the connecting lugs in the

pictorial.

Mount the fuse post with the special nut

provided. The rubber bushing goes on the

outside of the chassis. Note that there is

only one correct way for the post to be

mounted.

Insert the rubber grommet in the

hole

at the end of the chassis.

Mount the 10,000 ohm bias potentiometer

in the

hole near the pair of octal

sockets. Put the lockwasher on the shaft,

insert the control in the hole and fasten

at the top of chassis with the

nut.

Note orientation of connecting lugs.

Mount the five lug terminal strip and the

solder lug at the center of the chassis.

Insert a #4 screw from the outside. Place

the terminal strip over the screw, then

the small solder lug, then the #4 nut.

With #4 hardware, mount the cable

clamp loosely near the single octal socket.

Feed all the wires of the power trans-

former, PA-135, through the single hole

provided.

Fasten the transformer in

place with two #8 screws in the holes

nearest the front of the chassis using #8

lockwashers and nut<>. Now, from the

bottom, place the choke over the remain-

ing two transformer mounting holes and

fastcn both in place with two more sets of

#8 hardware. All but the black trans-

former leads go under the cable clamp

next to the rectifier socket; and then this

clamp may be tightened.

Mount the output transformer, A-470, on

the remaining set of holc-t; at the center of

the chassis. Note that the black, brown

orange, and yellow leads come through
