Model B-16
The antenna and ground installation is very im-
portant if the best possible reception is to be obtained.
The antenna should be erected in a clear space and as
high as possible, and should touch nothing but the
insulators at either end.We recommend a single
wire having an overall length of approximately 75
feet from the set to the far end.
An indoor antenna may be used if desired and
should be an insulated wire approximately 50 feet
-long, which ~ay be concealed behind wooden picture
mouldings or otherwise made inconspicuous.
A good ground is equally as important as the
antenna and it is suggested that the ground clamp
be attached to a water pipe, after the surface has
been cleaned.
Insert the antenna and ground wires through a
small hole near the rear edge of the shelf and attach
to the corresponding binding posts, which are located
on the chassis. See figures 2 and 6.

A power supplyof 100 to 120 volts, 60 cycle
alternating current isrequired.The exact voltageof
your power supplylinemay beobtained from your
local power company and any necessary voltage ad-
justment should bemade at thetime of installation of
the set.As shipped from thefactory, thisset is
adjustedfor a powersupplyin theno to 120 volt
range. If yourpower line delivers a voltage between
100 andno,adjustment maybe made through a
holein thebase under the powersupplyunit by
changing theterminal lug from one screw to the
other.See figure 1.In making this adjustment,it
is advisabletodisconnect the setfrom thepower
supply.

two large holes and the offset holes are designated as
the guide holes for the corresponding prongs of the
tubes and are shown in their exact positions.By first

The smaller figures near the upper edge of the dial
indicate frequencies in kilocycles. The volume of
reproduction may be varied by means of the control
at the left. Maximum volume will be obtained when
this control is turned all the way in a clockwise
direction.
The volume range switch provides complete control
of volume under all conditions. Position 2 gives maxi-
mum volume and is normally used. However, when
exceptionally loud signals are obtained,as in the
case of nearby broadcasting stations, and it is im-
possible to reduce the intensity of the signal as low
as may be desired by the volume control, the volume
range switch may be thrown to position 1.and the
sensitivity thus reduced to a point where it will be
possible to adjust the output to the desired intensity.
Use position 1.for strong locals and position 2. for
weak or distmnt stations.
starting the guide prong in the guide hole and holding
the tube in such a manner that the tube prongs line
up with the corresponding holes shown in figure 3
practically no difficulty will be experienced when
inserting the tubes in their proper sockets. Always
disconnect the set from the power supply when
changing or replacing tubes.
The dynamic reproducer unit supplied with this set
is connected to the set and the power supply unit by
means of a 4-conductor cable and two terminalsare
marked +and -, while the other two are marked
"Speaker." The terminals of this cable should be
plugged into thetip jacks correspondingly marked.
See figures 2 and 6. Do not touch these terminals
unless the set is disconnected or the p~wer turned
"off."
The power is turned on by a clockwise turn of the
knob on the right hand side of the panel as shown in
figure 4. The tuning dial will be illuminated, indi-
cating that the power is "on." In a few seconds, the
set will be ready for reception and the various sta-
tions may be located by turning the tuning control
which is the center knob. The dial is marked with
100 divisions and with figures for every 10 divisions.

SELECTOR TUNER
The Selector Tuner furnished on Brandes Radio
setsdoes not change the normal operation or tuning
of the set,but supplements it by providing a means
whereby the operator may readily select anyone of
anumberof predetermined stations. A series of but-
Fig. 5
tons will be found above the main tuning control and
these selector buttons may be adjusted to any desired
broadcasting station. See figure 5.
Having been once adjusted, the set may be tuned
to anyone of the stations by simply depressing the
8
button corresponding to the desired station and turn-
ing the tuning control knob until a latch engages
the button, after which the knob can no longer be
turned. If the volume control is adjusted for full
volume and the station is "on" a signal should be
heard.
To select another station, or to tune in the regular
way, first release the tuning mechanism by pulling
out the head of the button previously depressed, to
its original position. Next depress 'any other button
and turn the control knob as before. The indicator
in the center of the dial plate indicates the station or
button to which the set is adjusted and the direction
the tuning knob must be turned when changing from
one button to another.
The original adjustment of the station selector but-
tons is made as follows: .
Tune to the desired station in the regular
manner.
Dep(ess the nearest button, as indicated by
the pointer in the center, loosen the knurled col-
lar under the head of the button and move the
button until it engages the latch of the tuning
mechanism.
Carefu1'lj retune to maximum signal while
the button is free to move.
Tighten the knurled collar and the adjustment
is made permanent for future use.
Mark the station call letters on the head of
the button with waterproof India ink or a hard
pencil that will not smear.

beused to compensate for thevariation usuallyfound
in vacuum tubes. This adjustment is properlymade
when the set is tested at the factoryand it is sug-
gested that no change be made. However,in special
cases, should it be necessary to increase theregenera-
tion, thismay be done by tightening the adjustment
screw located below the holein thepanel.See
figure3.
To decrease the regeneration or to stop oscillation
loosen theadjustment screw.
Use a small insulated screw driver in makingthis
adjustment.
Thehum adjuster islocated on the chassis, as
shown infigure2.Should you hear an objectionable
hum, turn this adjusterslowly each way until the
hum is at a minimum. Reversethe position of the
A.C.connectioncableinthewall socket repeating the
above adjustment and use that method of connection
which produces theleast hum. Mark the plug so
that it may alwaysbe inserted correctly. This hum
adjustment should bepermanent unlessthe set IS
moved to anew location or thetubes changed.

PHONOGRAPH REPRODUCTION
Brandes Radio sets are provided with tip jacks for
use with phonographs for electric reproduction. In-
sert theleads from your phonograph pick-up and
volume contr~l in the tip jacks shown in figure2.
Tunethe radio set to a position where no radio signal
is received and excellent phonograph reproduction
may be obtained. DO NOT leavethepickup con-
nected when receiving programs by radio or the
quality o";eproduction will be spoiled.

If your set does not operate at whatyou think
should be its fullest efficiency:First,make sure that
the foregoing instructions have been fallowed and
11

that the antenna and ground installations are in good
condition. Finally take the tubes to your Authorized
Brandes Retail Merchant who will be able to test
them and tell you if new ones are needed. If the pilot
light burns out you can easily replace it by purchas-
ing a 2

h volt Mazda miniature lamp, No. 41.Simply
remove the old bulb from the spring clip and insert
the new one.It is essential that if you feel anything
serious is wrong with your Brandes set, you allow
no one but an Authorized Brandes Retail Merchant to
attempt to
fix it.
PLEASE DO NOT, UNDER ANY CIRCUM-
STANCES, RETURN BRANDES RECEIVERS TO
OUR FACTORY FOR ADJUSTMENT OR RE-
PAIRS UNLESS WE SPECIFICALLY REQUEST
YOU TO DO SO. CONSULT YOUR AUTHORIZED
BRANDES RETAIL MERCHANT FIRST.
