RCA Radiola Super-VIII Manual

Radiola Super
-VIII
INTRODUCTION
RADIOLA SUPER -VIII
is
a
radio broadcast receiving instru-
ment, utilizing the Super -Heterodyne principle
which
provides unusual simplicity
of operation, selectivity and
sensitivity.
The cabinet contains the operating mechanism,
a
loud speaker, and the
battery equipment,
as well as a loop
antenna,
making the set
completely
self-contained.
It
is
designed
for reception over the broadcast wavelength
band
220 to
550
meters (approximately
550 to
1350 kilocycles).
EQUIPMENT
Under the above name there
is
included the following
apparatus:
1
Radiola
Super
-VIII,
as
described
6
Radiotrons, Model UV
-199
BATTERIES REQUIRED
In addition, there are required the following
"A," "B"
and
"C"
batteries
which may
be obtained
from the dealer:
A-Six
standard dry
cells,
12
volts each, such
as those listed
below, for
lighting the filaments.
These are connected

INSTALLATION
Installing
Batteries. Access to the
battery
rack
is
secured by
removing the two screws
B
(Fig.
1)
(found at the center
on the
left- and right-hand sides
of
the upper panel
A,
on the rear
of
theecabinet)-which
releases the panel. Place two fingers
in
the
thumb
holes C, raise the rear panel, pushing it farther into
the slot
in
the top
of
the cabinet, then
pull
on
the
panel releasing
the lower end, which
permits the panel to drop down
free from
the set.
In the
middle and top compartments
will be
found
six
UV -199
Radiotrons,
two long red jumper connectors, and four
short yellow connectors. Remove these from
the rack and proceed
with the battery installation.
(A)
Place the
six
dry
cells
in
the
lower compartment,
three
in
the back
row and three
in
the front
row, taking
care
that
the outer binding posts
of all cells
point
in
the same direc-
tion. Connect the batteries
in two parallel groups, each
of
three
cells in series, as shown
in Fig.
1,
using the four short yellow
connectors E.
Before connecting these
batteries
to the set, make certain
that
the
desk fall
G
(Fig.
2
and
3) in the front
of
the set
is closed.*
Connect the lead marked
"
+A" (yellow), coming
through the
hole
in
the left-hand
side of the rack, to the two center binding
posts (not yet connected), and connect the other lead marked
-A"
(black with yellow tracer) to the two outside binding
posts.
or
or
or
or
or
*After the set
is
in
operation,
closing the desk fall
G
shuts
off
the operation
of the set completely.
When the user has kindled
with the set,
he need not turn any of the other controls,
but merely
.dose
the
desk fall.
(B)
Locate two each
of
the
"B"
or
plate batteries
in
both
the middle and upper compartments;
or
if 45 -volt blocks arc
used, place one
in each compartment.
Connect the two batteries
in
the upper compartment
in
series by using one of
the
long red jumper connectors
D, fastening
one end onto the
"+222
V." terminal
of one
battery,
and the
other end onto the
"
-
" terminal
of
the other battery.
(Should
the large
size
45
-volt blocks
be used, the two jumper connectors
will not
be needed.) Do similarly with the two batteries
in the
middle compartment.
Connect these batteries to the set, fastening the lead marked
"+B"
(red
in upper compartment, maroon
in
middle) onto the
battery terminal marked "+222
V.", not yet connected
(or onto
