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).

7. Adjusting Hum Controls-With the power still
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

MountingTurntable-In thecombination
Radiowith
Electrola move the electric pickup arm to the right as far
as possible.
Holding the turntable in both hands,
carefully
lower it over the turntable spindle. Make certain that the
slotin the turntableis
engagedu-ith
the pin in the spindle.
11. Regulating Speed-Regulate the speed
of the turn-
table to 78 revolutions per minute rvith the electric pickup
andneedle
on the record.
This can
bedonebv placing
i piece
of paper
under
theedgeof the recordon theturntabli, count-
ing the number of revolutions
for one minute, and turning

speedof 78 revolutionsper minute is
obtained. RADIO OPERATION
Referringto Fig. 2 for locationof the controls:

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
calibration at which the station is received,
and the
station call lettcrs then marked vertically as shown in Fig. 2.
ELECTROLA OPERATION
Rcferring to Figs.2 and3 for the locationof the controls
l. Turn the transfcr sw'itch

eccentricgroove.) When playingrecords
without the eccentric
groove-,
stop the motor by pushingthe motor starting switch
toward the rear of the cabinet. Snap the power switch on
the radio panel
to the left to its "off" posiiion.
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.
