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.

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

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

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

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-

REGENERATION ADJUSTMENT

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

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

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.
