Location of Coils and Trimmer Adjustments
The first i-f transformer is mounted on top of the thassis deck to the right of the variable condenser. The trimmers are accessible through holes in the top of the can.
The second i-f transformer is mounted on top of the chassis between the variable condenser and the speaker. The trimmers are accessible through holes in the top of the can.
The trimmers for the antenna and oscillator coils are located on the variable condenser. The trimmer on the front section is for the oscillator coil.
The oscillator coil is located underneath the chassis. The loop antenna acts as the antenna coil.
An oscillator with frequencies of 455 and 1400 kc is required.

GENERAL INFORMATION
Model H-400 is a compact four -tube AC -DC tuned radiofrequency receiver that tunes the standard broadcast band of
frequencies and one police band. One side of the power line is connected directly to the chassis ground; therefore, caution
should be exercised in servicing.
to WinhseenrtotpheeraptoinwgefrropmluagDwCitshotuhrceeporfoppoewr eproiltairsityn.ecIefsstahrey
receiver fails way, reverse
to function with the power the plug. If any hum is
plug inserted noticed when
one
the
receiver is used on A -C, reverse the power plug as above.
ALIGNMENT
Connect the high side of the signal generator through a 100-mmf condenser to the terminal to which the antenna hank is soldered. The low side of the signal generator output should be connected to the receiver chassis through a .05 mfd. condenser. Connect a suitable output meter across the voice coil leads; then proceed as follows:
I. With gang condenser plates completely closed, the tuning index should be over the last calibration mark on the
dial. 2. Set volume control to about Yi of maximum.
3. Rotate gang to minimum capacity and tune trimmers on the gang condenser to 1750 KC signal. Re -tune gang to 1500 KC signal and peak trimmers by alternate adjust-
ment.

NOTE A - DIAL CALIBRATION: in order to adjust the receiver correctly the dial must be aligned to track
properly with the tuning condenser. To adjust the dial, proceed as follows: With the tuning condenser closed (maximum capacity), set the dial pointer on the extreme left index line at th. low free . end of the broadcast scale. The arrangement of the drive cable and dial
pointer is shown
NOTE C - If two peaks (signals) are ob d on the
aligning meter when adjusting the oscillator padder No.
29B, tune the padder to the
d peak from the maxi-
mum capacity position (screw all the way in).
NOTE D - II two peaks (signals) are observed on the aligning meter when adjusting the loop padder RA, tune the padder to the first peak signal from the maximum capacity position (screw all the way in). When adjusting the padders to this first peak roll the tuning cond (rock) *lightly back and forth to obtain the maximum
readings on the aligning meter.

Antenna Installation :
In most cases, the antenna should not be installed per-
manently on the apartment or residence roof until the quality
of the picture reception has been observed on a Television
Receiver. A temporary transmission line can be run between
receiver and the antenna allowing sufficient slack to permit
moving the antenna. Then, with a telephone system connect-
ing an observer at the receiver and an assistant on the roof
to find an antenna location, the antenna can be positioned to give the most satisfactory results on the received signal.
A shift of only a few feet in antenna position or direction
may effect a tremendous difference in picture reception. Whenever possible, the antenna location should be chosen
or erected so the antenna is not only oroadside to the trans-
mitter but removed as far as possible from highways, hospitals
and doctors' offices, and similar sources of interference. Auto
ignition and diathermy apparatus may cause noise inter-
ference which spoils the picture.
In mounting any antenna, care must be taken to keep the
antenna rods or pickup wires proper at least 1/4 wave length
(at least 6 feet) away from other antennas, metal roofs and
gutters or metal objects. Under certain extremely unusual conditions,
it may be
possible to rotate or position the antenna so it receives the
cleanest picture over a reflected path. If such is the case, the
antenna should be so positioned. However, such a position
may give variable results at the nature of reflecting surfaces
may vary with weather conditions, as a wet surface has been
known to have different reflecting characteristics than a dry
surface.
In short, a television receiving antenna and its installation
must conform to much higher standards than an antenna for
reception of International Short Wave and Standard Broad-
cast signals because:
(1) Intervening obstacles have a pronounced shielding
effect on the ultra -high frequency waves producing low
intensity signals. Severe trouble with multi -path transmissions
may be experienced, especially in congested city areas.
(2) The picture signal is comprised of a very wide band or
range of frequencies, all of which must be received with
No attempt should ever be made to measure the high (2,000 volts) voltage, because of the dangers and difficulties involved. If at any time it becomes necessary to service the high voltage circuit, the suspected parts should be replaced by parts known to be in good operating condition.
Always replace the red can over the 879 high voltage
rectifier.
The most dangerous portion of the receiver is the plate (top cap) lead for the 879 high voltage rectifier. Always be very careful when working near or with this lead.
When working on the high voltage supply portion of this chassis, the following precautions should be observed:
1. Remove power supply cord from the power supply
socket.
2. Use only one hand at a time. 3. Connect a shorting lead between ground (firstly) and
to the high voltage side. 4. Whenever working with the oil -filled high voltage
filter capacitors, keep a constant short across the capacitor, as these capacitors do not completely lose their charge after being discharged a single or several
subsequent times.
5. Only one person at a time should work on the unit to prevent any misunderstanding which may result in
an accident. When it is desired to measure any voltages on the Video
good efficiency.
(3) It must be continually remembered that the discernment of the eye is much more critical than that of the ear.
portion of the chassis, the primary leads of the high voltage transformer should be disconnected and taped together.
When any changes are made on the Video portion of the
chassis, the locations of leads and parts should be returned

2. If the picture "tears out" when the receiver is jarred it may be due to microphonic 1852, 1853, or 6J5 tubes.
3. The 6J5 oscillator tube should be removed without rocking it in its socket to loosen it, as the motion may cause the 80.5 mmf capacitor C16 to break off.
4. The coils or straps in the h.f. oscillator circuits should not be touched or moved or the alignment of the receiver will be disturbed.
5. The insulator on the high voltage filter capacitors may become dirty and break down to short out the high voltage.
6. The two Video coupling capacitors C44, 45, should be kept clear of chassis.
7. In some cases the metal Kinescope mounting shield may become magnetized by the earth's or some nearby magnetic

MODEL 0-50 PORTABLE VICTROLA
(phonograph only)
The Model 0.50 Portable Electric Victrola consists of a crystal pickup, a two -stage audio amplifier, and eight -inch electrodynamic speaker, and a motor turntable mechanism with automatic mercury switch for starting and stoppingall housed in a portable carrying case of modern design and
appearance.
The phonograph motor is a self-starting, constant -speed induction type. It should be lubricated every six months by applying a few drops of light machine oil to the spindle bearing and oil hole.
The motor spindle is tapered, and a conical rubber piece fits snugly on the spindle. The hole in the turntable bushing
is tapered to fit the rubber. This provides an excellent self centering floating mounting.
A metal washer is placed on the spindle under the rubber piece. The washer has ears on the under side which fit over a pin that projects through the spindle.
The motor switch is automatic for both starting and stopping, and when properly adjusted, will turn the motor on as the pickup is moved from the pickup rest toward the turntable. The switch should be adjusted so that it will snap into the "off" position when the pickup needle is 13/4 inches from the center line of the spindle. The motor may be shut off at any time by placing the pickup on the pickup rest.

INSTALLATION OF NEW BATTERIES. To install new batteries remove
the two large screws located on the ends of the case by inserting a small coin in the slot of the screws and turning. Open the case as shown in the accompanying illustration. The batteries can be readily removed and new ones used to replace them. The "A" cells must be inserted with the ends having the brass caps pointing in the direction shown in the diagram. Be sure the contact springs are clean before installing new "A" cells. If the contacts are dirty or corroded, scrape them off with a knife before installing new cells.
CAUTION. Never leave dead batteries In the receiver or store the receiver with the batteries In it for long periods as the batteries are apt to swell and damage the radio.
To insure maximum battery life from your receiver do not allow the batteries to become heated or damp and use the batteries while they are new. Batteries deteriorate with beat, moisture and age.

These readings taken using a voltmeter of 1000 ohms per volt.
NOTE A: The bias on the 25L6GT grid is: on 03-6J chassis: --4 volts measured across resistor No. 12; on 03-61. chassis: - 5 volts measured across choke No. 63.
X NOTE B: Due to the high resistance of resistors No. 20, 6, and 13,
only a small voltage will be read at the plate of the 6SQ7 when using a voltmeter having a resistance of 1000 ohms per volt.

WHEEL STATIC: Wheel or brake noise is probably the most peculiar type
of interference and is due to accumulated static charges. This

type of interference is only noticeable while the car is in mo-
tion and could very easily be confused with ignition interference. Check for this with car running at a good speed, turn
the ignition switch off and the clutch disengaged, apply the brakes. If the noise stops, the source of the static is in the wheels. To overcome the wheel static condition, use graphite grease in the wheel bearings or insert grounding springs in the hub caps. In the case of external brakes, it may be necessary to ground the brake bands to the frame of the car.
