DESCRIPTION
The mcst outstanding developments
in the fields
of radio
and record reproduction are offered in the new Victor Radio
and Victor Radio with Electrola.
Embodied in thesenew instruments are all the features
which are essential
to the listener's
completeenjoyment and
appreciation-quality musical reproduction, simplicity and
economy
of operation, and a high degree
of sensitivityand
selectivity.
The reproducing system comprisesthe radio unit, the
power-amplifier,
and the electro
dynamic reproducer. In the
combination Radio with Electrola the electricpickup is used
to translate
into electrical
energy
the mechanical
vibrations
of
the needle
in the recordgrooves. Unsurpassed
tone quality
and controllable
volume without distortion
for both radio and
recordreproductionareobtainedthrough the power-amplifier
and electro
dynamic reproducer.
All power for operationis obtained from the electric
light
line, and is controlled by a small snap switch on the radio
panel.
The tuning range of the instrument covers the entire
broadcast
band of 550to 1500
kilocycles
(545
to 200meters).

turned on, placethe transfer switch, shown in Fig. 2, in the
recordpositionto the right. With a small screw
driver,,
turn
the UX-226 hum control in the power-amplifier
unit, shown
in Fig. 1,slightly in either directionas
required
until the hum
of the instrument is a minimum. Turn the transferswitchto
the left to the radio position and alsoturn the radio volume
control to the left. With a small screw
driver, turn the UY-
227hum control in the radio set (see Fig 1) to the right or
left asrequireduntil the hum is a minimum.
Improved reception
and reduction
of hum may sometime,s
be effettedby reversing
the prongsof the power supply cord.
This can be done by removing the power plug, turning it
through a half circle,and reinserting
it.
Excessive
hum may sometimes
be causedby one gf the
Radiotrons not functioning properly,
particularly theUY-227.
A new Radiotron should
be tried i{ this conditionis noted.
8. Rearranging Radiotrons-Improved reception can
sometimes
be effectedby rearranging
the RadiotronsUX-226
iri their various sockets
in the radio set and listeningto the
reproductionuntil the best combination is found.
9. Harmonic Modulator-The harmonic modulator,
which controlsemphasis on the basssection
of the scale,
can
be regulated to suit individual preference
or the acoustic
qualitiesof an unusual room. This control, shownin Fig. I'
is set in the factory for the best reproduction
over the entire
musical range, and should not ordinarily require further

LOGGING STATIONS
The oositions on the sclector scale at which difrerent
stations are receivcd can be markcd on the light space pro-
vided if desired. The slot on the indicator is so shaped that
the scale
can be accurately marked w-ith a soft lead pencil to
ensure
ease
of crasure. It w'ill be noted that the scaleis cali-
brated directly in kilocy'cles,
so
that the lorv
{requency stations
(high u'ave length) will be rcceived tou'ard the left end and
ihJ ttigl'r frequency stations (lorv u.ave. lergth) toward the
risht end of the scale. A short line should be placed opposite
th1 scale

GENERAL INFORMATION
1. Antenna-fn seneral
the bestr€surts
will be obtained
by usinga single
wirJoutdoor antenna. It should
befrom 50
to 75,f.eetlong including the lead-inand ground wires,
which
shouldbe
short
anddirect. A lonEerantennawill increase
the
sens,itivity
and decrease
the selectivity,whiletheopposite
will
apply to a shorter
antenna. The antenna
shouldbe isolated
from other objects and as high as possible. It should be at
right angles
to electriclight, traction, power, and other wire
lines,
and shouldnot cross
either above
or belowsuchlines.
The antenna shouldbe supported
at both endsby glazed
porcelain or glass insulators. The lead-in wire should pre-
ferably be a continuation of the antenna wire. If ii is
necessary
to make a connection between the antenna and
lead-inwire, or between
sectionsof either,these
joints should
be securely soldered
together. The lead-in wiie should be
brought through the wall or window frame, and insulatedby
means
o{ a porcelain
tube. It is important that the antenna
and lead-in should not make contact with any object except
the insulators. When an outdoor antenna is used.it should
be protectedby means
of an approved
lightning arrester.

IWhere the installation of an outdoor antenna is not
practicable, satisfactory results may be obtained by..
using
lUo"i SOf""t of ordinary double iotton covered bell wire
(No. 18B. & S.)strung
around
the pict-uremolding. It,,may
alsobe run the length
of the attic. Such
an antenna
wlll not
be satisfactory
in a'building with metal lath under
the.
plaste
r'
An indoor antenna is not as efficientas a properly.lnstallecl
outdoor antenna. Variouspossiblearrangements
shouldbe
tried if the first is not satisfactory.
2. Ground-A good ground is as necessary
as.a good
antenna. The bestg"round-is
a good
electrical
connection
to a
water pipe. If thii is not con"venient,
a connectionto the
.t.rrn 'oi hot water heating
system
may be tried. Connec-
tionsto gas
pipes
should
.toi b" used. If none
of those
recom-
mended
""Uo""is available,
a pipeor metal rod may be driven
into the groundto a deptlrof 3 or 4 feet,
preferably
where
the
soilis m5ist. The groundconnection
should
be made
with a
g.ound clamp, the"wire being soldered
or held.by clamping
under a screw
or nut. Be sure
to scrape
and clean
tle PlPe
thoroughly before attaching
-
the ground clamp'. A Pgor
ground connectionmay not be ap-parent
on local receptlon
6ut it is an importani factor in diitant reception' Usuallv
connection to more than one ground, for instance to both
water and steam
pipes,
will improve reception.
3. Radiotrons-The only parts ordinarily requiring re-
placement
will bethe Radiotioni. These
shoild lastfor many
months if not abused
either by rough handling or by opera-
tion at too high voltage. The latter may-be
caused.by
oPerat-
ing the instniment wien the voltage
of'thepowerline exceeds
120volts.
Often improved reception
may beobtainedby interchang-
ing the Radiotrons
UX-226 as described
on page 6' -This
miv be the case
even
when the Radiotrons
are new' In no
."i!, ho*"*'er, should
any of thelJX-226 Radiotro-ns
be.placed
in tire IJX-2+3 or UX-280 sockets since the higher filament
voltage
would burn out theUX-226-
It is recommended
that one or two spareRadiotrons of
each type be kept on hand for emergencyuse.. 'I hls wlll
afiord i6me assui".rce
againstannoying interruptions due to
the possible
failure of i Radiotron, and will permit ready
deteition of any Radiotron not operating
properly.
4. Care of Cabinet-Victor cabinet cleaner is recom-
mended
for cleaning
and polishingthe cabinet. This Prepara-
l0

tion can be used freely u'ithout injuring the finish o{ the
cabinet. The cleaner
can be ourchasedfrom anv Dealer in
Victor products.
5. Care of Records-Records should be kept as free
from dust as possible. Gritty dust on the record not only
wears
out the recordrapidly, but causes
harshand unpleasant
reproduction. The recordsshould not be exposedto severe
heat, and should be cleaned
only by brushing with e velvet
or plush pad. If a recordbecomes
crackedor badly scratched,
it is best to destroy it. Playing a scratched or imperfect
record
may resultin injury to the electric
pickup.
6. Electric Pickup-Imperfect Reproduction-A loose
needle
may causenoisy reproduction. Hence, if your Elec-
trola reproduces
improperly, seethat the needle
is securely
fastened
in the electricpickup.
If you are using steelneedles,
put in a new needleafter
every record. The Tungs-tone needle
can be used until the
reproduction becomes
imperfect. The Victor full-tone steel
needle
or full-tone Tungs-tone
needles
give the bestreproduc-
tion, and only Victor needlesarerecommended.
If noisy reproduction should develop and tightening or
changingthe needlesdoesnot eliminate the condition which
persists
with various records,it is possible
that the electric
pickup is injured or out of adjustment. Take the pickup
to a dealer in Victor products for repairs.

7. Lubricating Motor-The Electrola motor should be
kept clean and should be lubricated at least once in six
months. To oermit readv inspectionand lubrication of the
motor, ."-ovi the turntable and the four screwsat the cor-
nersof the Electrola motor board. Lift up the front edgeo{
the motor board. The parts requiring lubrication are shown
in the oiling diagram, Fig. 4. Before lubricating, wipe the
motor with a clean cloth dampened with kerosene. The
properlubricants requiredfor the motor can be secured
from
any dealer in Victor products, and only Victor lubricants
are recommended. Samples of the proper lubricants are
furnishedwith the instrument.
8. Failure in Operation-Should the instrument at any
time become inooerative. or its oDeration become unsatis-
factory, determine first that it is b^eingsuppliedwith power
by observingif the operating lamp in the rear of the tuning
scale
is lighted when the power switch is on. Then observe
if
all the Radiotrons in the radio set and the power-amplifier
arelighted.
Even thoughall the Radiotrons seemto light, the
trouble may be due to the improper functioning of one of
theseunits or to a poor contact in one of the sockets. Dis-
connect the power supply cable from the instrument by
pulling the powerplug. Removeall the Radiotronsfrom their
sockets,
one at a time, and clean
the contact pins with sand-
paper. Wipe the pins care{ully; then slidethe Radiotron in
and out of its socket several
times. If the operation is not
yet corrected, replaceeach Radiotron, successively,
with a
new oneof the propertype until the poor oneis detected.
If the instrument still operatesimproperly, examine the
connections
of the antennaand sround. Theseshould all be
goodmetallic connectionsfreefrom any corrosion.
9. Service-The tests described above can be readily
carried out, but you should look to your Victor dealer for
assistancein caseof trouble. Ordinarily, arrangements
canbe
made with the dealerfor a periodicalinspectionand test of
the instrument at a reasonable
price. He iscapable of render-
ing efficient service,and it is recommended
that you take
advantase
of this service.
