TUBE SOCKET VOLTAGES

Socket voltages are shown on the Schematic diagram at the tube socket terminals. All voltages are between the socket terminal and chassis ground. Plato, screen and cathode voltages were taken with a 1000 ohm-per-volt meter with a 300 volt scale used for plate and screen voltages. Audio grid voltages were read with a vacuum tube volt-meter. Conditions of measurement ore:

Line voltage 117 Volts AC Signal Input None A variation of ±10% is usually permissible.

•POINTER CLAMP

DRIVE CORD REPLACEMENT

Use a new 10X68 drive cord assembly or a new length of cord 46 inches long for the installation, winding three turns clockwise around the drive shaft with the turns progressing away from the chassis. After completing the installation, rotate the drive shaft a few turns to take up the slack in the cord.

MODEL D-3]

IpEJVKRAL description

This model is a 3-way portable radio with 4 tubes plus a selenium rectifier and uses a built-in antenna. The receiver will operate on 115 volts, 50 to 60 cycles AC, or 115 volts DC, or on the self-contained batteries. When using the radio on AC, reversing the plug may reduce hum. If the radio does not operate in one minute on direct current (DC), reverse the plug. When bat-

tery operation is desired, the line cord plug is ins- Into a socket switch on the chassis (see bottom ca view), the insertion automatically moves the switch tacts for battery operation. When the line cord pi out of the chassis switch, the batteries are automatl disconnected.

VOLUME and ON-OFF SWITCH

OPERATION

OFF-ON SWITCH AND VOLUME CONTROL TUNING KNOB

The knob on the left Is both the on-off switch and the volume control. When the control is turned ail the way counter-clockwise, the set is off. A slight clockwise rotation will click the switch and turn the set on. The knob may then be used to regulate the volume. Be sure your set is turned completely oft when not in use; otherwise the tubes will wear out and/or the batteries will be discharged unnecessarily.

The knob on the right is the tuning knob; rotati^ this knob moves the indicator along the dial scale. \ selecting a station turn the knob back and forth the tone is clearest and loudest. Do not use the t knob to regulate volume; the volume control shoul used for that purpose after the station selector has tuned in properly.

ALIGNMENT PROCEDURE

The Alignment Procedure below includes the sensitt* vities at the input of various stage. All measurements are based on an output of 50 milliwatts. This may be measured by disconecting the speaker voice coil and substituting a 3.2 ohm, 5 watt resistor across the secondary winding of the output transformer. A reading of .4 volts AC across this resistor will be equivalent to a

50 milliwatt output with speaker connected. The volume control must be set to maximum.

The signal source must be an accurately calibrated signal generator capable of supplying the frequencies designated, modulated 30% with a 400-cycle audio signal. A 400-cycle audio signal is required for the audio measurement. Variations in sensitivities of plus or minus 25% are usually permissible.

INSTALLATION

Ploce the receiver upright on a table or other level surface convenient to a power outlet. Do not place it on or near a ra tor or heater.

This receiver is designed to operate from a 117 Volt A C or D C source of supply. On A C, improved reception sometimes be obtained by turning the plug halfway around and reinserting it into the power outlet. Try it both ways leave it in the position which gives the best reception. On D C, the receiver will operate with the plug inserted in only position.

ANTENNA

A 15 foot honk antenna is attached to the receiver which should be uncoiled and stretched out to its full length best reception. Run the wire around the room floor and around window frames for good signal pickup.

In locations of low signal areas an Outdoor Antenna will greatly improve reception and our Western Auto Aerial J Numbers 3D5111 and 3D5110 will prove highly satisfactory by increasing the reception volume level.

This receiver is designed to operate without a ground connection and no attempt should be made to use one.

OPERATION

Insert the power cord plug into the power receptacle. To torn the receiver on, turn the Volume Control knob loc< on the right side of the receiver until a click is heard. In about 30 seconds the set will be in operating condition. Tun the Volume to the right or clockwise increases the volume.

Tune in stations by turning the large center tuning knob. The numbers the tuning knob passes over, show Kilocy with the last two ciphers left off. For example number 9 is the location of 900 Kilocycles. As you have tuned in the sta desired move the toning knob to the position which produces the deepest rounded tones with a minimum background n< and clearest reception.

To turn the receiver off, torn the volume knob to the left or counter clockwise position until a click is heard.

Align for maximum output. Reduce input as needed to keep output near 0.4 volts.

The alignment procedure should be done in the order given for greatest accuracy.

Always keep the output from the generator at its lowest possible value to prevent the AVC of the receiver from interfering with accurate alignment.

ANTENNA Two antennas are incorporated in the receiver, a True-

tone Stratoscope Loop Antenna for the broadcast range and a folded dipole antenna for the FM (frequency modulation) range. For the reception of local or powerful nearby stations, or in areas where the signal strength is good, usually no other antenna will be required. However, in some locations for the reception of FM stations, or dis- tant stations in the broadcast band, an outside antenna is essential.

As the need for an external antenna varies indifferent locations, it is suggested that the radio be tried with the two antennas In order to determine if an external antenna is needed. If it is felt that on additional antenna is needed a folded dipole antenna with a 300 ohm line lead-in should be used. This typo of antenna will increase the signal pickup on the FM band. Attach two terminal clips (packed in the literature envelope) to the lead-in of the outside FM antenna. Then connect the lead-in to the terminal strip at the roar of the receiver (see tube position illustration.)

It should be remembered in conjunction with the erec- tion of an FM folded dipole antenna that FM reception is usually limited to "line of sight" distances or op to about 45 miles. Before erecting a special antenna for FM reception it is best to make certain that on FM station exists in your area.

For some locations FM reception may prove satisfactory with the dipole antenna but an external antenna may be needed for broadcast reception. For these ranges a terminal is attached to the loop antenna to which an external antenna may be connected. The antenna should be 50 to 60 feet long, with not more than 30 feet of lead-in and should be erected as high as possible and at right angles to the nearest electric lines.

NOTE: An external ground connection is not required.

TUBES AND DIAL LAMP The type designation of each tube is' stamped on the

tube and the radio chassis base. The correct positions in which the tubes must be installed are shown in the tube position illustration.

The tubes in the radio should be checked periodically by taking them out and having them tested.

When replacina the tubes, be sure that tfjey are inserted in the proper sockets. To install a tube, insert the center guide pin into the center hole of the tube socket and turn the tube until the key drops into position. Then push the tube down until it is held firmly in the socket. To install a tube into a miniature type tube socket, line up the tube prongs with the holes in the socket and then gently posh the tube down until it is held firmly in the socket. All tubes must be In their sockets to operate the radio. Use only No. 47 dial lamps.

IF THE RADIO FAILS TO OPERATE SATISFACTORILY

Recheck the foregoing instructions. If the radio still radio, take them to your local radio dealer and have them does not appear to operate satisfactorily, proceed as fol- test®d either by moans of a tube tester or by inserting lows: , them in a radio that is operating satisfactorily.

FIRST-Check Power Supply. Be sure there is power ot the convenience outlet to which the radio is connected. To determine this, connect a lamp to the outlet and see whether or not the lamp lights.

Check the voltage and frequency of the power supply with that shown on the power rating label on the radio. If there is any doubt concerning the power supply, with- draw the plug from the outlet and consult the local power company before reinserting the plug.

SECOND—Check Tube Positions. See that the tubes are in the correct sockets as shown in the illustration.

Moke certain that the tubes are operating. (Gloss tubes will light very dimly.)

THIRD—Check Antenna. If on outside antenna is being used, inspect the antenna system to see that it it in good condition and not grounded at any point.

FOURTH—Test Tubes. Remove the tubes from the

FIFTH—Service. If the radio does not function properly after the above procedure has been followed and the tubes have been tested, get in touch with the dealer from whom the radio was purchased or call in a competent radio technician.

FAULTY FM RECEPTION

The requirements for FM reception are more critical than for Standard band broadcast or si-.ort wave reception. This includes the area in which the receiver is located, the type of antenna used, the distance the receiver is located from the station to be received and other factors not encountered in Standard bond broadcast reception. It is to bo noted that reception in the high frequency FM band is usually limited to 'line of sight" distances or up to about 45 miles. Also tall buildings or other structures between the transmitter ond the receiver may bo found to affect reception. Rwception under these conditions will sometimes be helped by the addition of an external folded dipole antenna with a 300 ohm tine lead-in. Information concerning this is given in the Antenna paragraph.

PRODUCTION CHANGES IN V-2157-5 CHASSIS

WIRING CHANGE TO PREVENT "MOTOR- BOATING" — In later production, a possible cause of motorboating is eliminated by a slight re- arrangement of wiring. The changes, which are physical in nature and involve no schematic changes, are illustrated at the right. If motorboating occurs in a chassis that does not contain the change, proceed as follows:

1. Remove the wire that is connected between pin #6 of the 50C5 and the 2nd I-F transformer.

2. Disconnect lead $1 of the multiple capacitor and resistor assembly (Zl) from the 2nd I-F transformer, and connect it to pin S6 of the 50C5 socket.

3. Connect an insulated wire between pin #6 of the 50C5 socket and pin #6 of the 12BE6 socket.

INCREASE IN WATTAGE OF RIO - In later production, the wattage of RIO (22 ohms) is increased from ^ w, to I w. to prevent resistor burn-

FIG. 3 - DIAL DRIVE

MODELS H-331P4U AND H.333P4U

The following changes are incorporated in latei production of the V-2164U chassis:

1. To improve the operation of the HF oscillator at low line voltage, the dropping resistor for the pin #3 grid of the 1R5 tube (R2) is changed to 22,000 ohms, and the grid return resistor for the 1R5 and 3V4 tubes (R4) is changed to 150,000 ohms.

2. An improved line-battery switch (SW2) is used in later production. In chassis containing the improved switch which is designated V-10426-2, the 82 ohm resistor (R22) in series with the positive lead of the B battery is not used, and the battery is connected directly to the switch.

3. To prevent B battery leakage when the line plug is inserted for battery operation and the on- off switch is in off position, the connecting points for the negative lead from the A battery and the negative lead from the B battery are interchanged. The negative lead from the B battery now connects to the point where the A battery negative lead previously connected, and vice versa.

The parts list should be changed to read as follows:

R2 RC20AE223M Resistor, 22,000 ohms lA w I.05

R4 RC20AE154M Resistor, 150,000 ohms A w 04

SW2 V-10416-2 Switch, line-battery 1.15

AOE

MODELS H.331P4U AND H.333P4U

The following changes are included in later production:

1. In some chassis, a 12 mmf capacitor (C12) is added in parallel with the antenna tuning sec- tlon of the variable capacitor (Cl) to assure that the antenna circuit can be aligned correctly.

2, CIO, connected from common negative to the filaments of the IR5 and 1U5, is removed from the chassis.

MODEL H7235 Ch. 7H04Z1

The 7H04Z1 chassis incorporates a supernetcrodyne circuit with two stages of IF, on the FM Band, and two stages on the AM Band, There is one stage of RF amplification on the FM Band.

When adjustments are made on the 7H04Zlor any AC-DC chassis, a line isolation transformer (I10-V input to 110-V output) is recommended in order to avoid a "hot" chassis. If an isolation transformer is not available, check the AC voltage between chassis and bench ground, and if there is any indication of voltage, reverse the plug before handling the set.

The IF transformers and the discriminator transformer arc the new permeability tuned type. The advantage of an IF transformer of this type is its extreme stability under various humidity and temperature conditions. The upper coil is the secondary and the lower the primary. When adjusting these IF and discriminator transformers, tuning wrench 68-19 can be inserted into the top slug, rotated until maximum output is obtained and then dropped down to the lower slug and the same operation repeated. The tuning wrench is so designed that turning one slug does not affect the adjustment of the others.

FM IF Alignment; Keasonably accurate alignment can be made by following the pro codure outlined in this service note.

FM Discriminator Alignment: When the secondary of the discriminator is aligned (operation 5) use sufficient signal input to get a good positive and negative indication before setting the slug for zero reading. A center zero indicating meter is recommended for this adjustment, but is not absolutely necessary. Reversing the leads of a non-zero center meter, or observing closely when the meter starts to go to the left (negative) of zero will give the same results.

Alignment of this chassis will, in most cases, be unnecessary unless an IF or RF transformer is replaced or the adjustments have been tampered with.

Correct alignment can only be made if the following procedure is followed;

A vacuum tube voltmeter with isolation resistor of 2,000,000 ohms in series with the hot lead will serve for FM adjustments. This lead should be shielded.

An AC output meter connected across the primary or secondary of the output transformer will be satisfactory for all AM adjustments.

The signal _generator_ output .should be kept just high enough to get an indication on the meter.

(a) Vacuum Tube Voltmeter Lug 7 on discriminator transformer to chassis (half discriminator load). (b) Vacuum Tube Voltmeter Lug 5 on discriminator transformer to chassis (full discriminator load). (c) Vacuum Tube Voltmeter from Limitcr Grid to Chassis. (d) Loosen Slugs by applying a hot iron to the cement.

MODEL H724Z2,Ch. 7H022 The 7H0?,Z2 chassis incorporates a superheterodyne circuit with two stages of IF, on the FM Band, and two stages on the AM Band. There is one stage of RF amplification on the FM Band.

When adjustments are made on the 7H02Z2 or any AC-DC chassis, a line isolation transformer (110-V input tollO-V output) is recommended in order to avoid a "hot" chassis. If an isolation transformer is not available, check the AC voltage between chassis and bench ground, and if there is any indication of voltage, reverse the plug before handling the set.

The I»F. transformers and the discriminator transformer arc the new permeability tuned type. The advantage of an IF transformer of this type is its extreme stability under various humidity and temperature conditions. The upper coil is the secondary and the lower the primary. When adjusting these IF and discriminator transformers, tuning wrench 68-19 can be inserted into the top slug, rotated until maximum output is obtained and then dropped down to the lower slug and the same operation repeated. The tuning wrench is so designed that turning one slug docs not affect the adjustment of the other. FM IF Alignment: Reasonably accurate alignment can be made by following the procedure outlined in this service note,

FM Discriminator Alignment: When the secondary of the discriminator is aligned (operation 5) use sufficient signal input to get a good positive and negative indication before setting the slug for

zero reading. A center zero indicating meter is recommended for this adjustment, but is not absolutely necessary. Reversing the leads of a non-zero center meter, or observing closely when the meter starts to go to the left (negative) of zero will give the same results.


Correct alignment can only be made if the following procedure is followed:

A vacuum tube voltmeter with an isolation resistor of 2,000,o00 ohms in scries with the hot lead will serve for FM adjustments. This lead should be shielded.

An AC output meter connected across the primary or secondary of the output transformer will be satisfactory for all AM adjustments.

The signal generator output should be kept just high enough to get an indication on the meter.

(a) Vacuum Tube-Voltmeter-Lug 7 on discriminator transformer to chassis (half discriminator load).

(b) Vacuum Tube Voltmeter Lug Son discriminator transformer to chassis (full discriminator load).

(c) Vacuum Tube Voltmeter from Limiter Grid to Chassis.

(d) Loosen Slugs by applying a hot iron to the cement.

The 10H20Z chaa#i« incorporatea a auperheterodyne circuit with two stages of IF, on the FM Band, and two stages on the AM Band. There is one stage of RF amplification on all bands.

FM RF Alignment: The tuning slugs arc attached to threaded shafts and the alugs are varied in the field of the coils by turning the shafts clockwise or counter-clockwise. After adjustment the shafts must be secured with a drop of speaker cement.

AMandFM Alignment: The AM and FM IP transformers in this reciever are of the new permeability tuned type. The advantage of an IF transformer of this type is its extreme stability under various humidity and temperature conditions. The upper coil is the secondary and the lower the primary. When adjusting these IF transformers the tuning wrench 68-19 can be inserted into the top slug, rotated until maximum output is obtained and then dropped down to the lower slug and the same operation repeated. The tuning wrench is so designed that turning one slug does not affect the adjustment of the other.

FM IF Alignment; Because of the wide band pass, it is desir- able to use a FM signal generator and a cathode ray oscilloscope when aligning the FM if channel.

If visual alignment equipment is unavailable, reasonably accurate alignment can be made by following the procedure outlined below.

FM Discriminator Alignment: When the secondary of the discriminator is aligned (operation 5) use, sufficient signal input to get a good positive and negative indication before setting the slug for zero reading. A center zero Indicating meter is recommended for this adjustment, butis not absolutely necessary. Reversing the leads of a non-zero center meter, or observing closely when the meter starts to go to the left (negative) of zero will give the same results.

The I.F, transformers incorporated in this receiver are of the new permeability tuned type. The advantage of an I.F. transformer of this type is its extreme stability under various humidity and temperature conditions. The upper coil is the secondary and the lower the primary. When adjusting these I.F. transformers the tuning wrench 68-19 can be inserted into the top slug, rotated until maximum output is obtained and then dropped down to the lower slug and the same operation repeated. The tuning wrench is so designed that turning one slug does not affect the adjustment of the other.

In the event the receiver oscillates during phono operation, adjust Cl6 4-80 mmf. capacitor to a point at which the oscillation ceases.
