 DELCO RADIO
 OWNER'S MANUAL

 MODEL 633




INSTALLATION AND OPERATING INSTRUCTIONS


This model of the Delco Radio is a six-tube super-heterodyne receiver
designed for operation with a HEADER type speaker. It comprises the best
in automotive radio engineering, featuring Syncro-Tuning--the newest,
most efficient antenna circuit yet developed, and Sensitivity Control.

The speaker and remote control unit are supplied in separate packages
and are available in a wide variety of types and styles, depending upon
the make and model of car the unit is to be used on.

The package contains:

INSTALLATION


=Antenna--=

See Instructions in antenna package.


=Chassis--=

This receiver may be installed on any car with Positive or Negative
ground without any changes of wiring.

When possible, locate the chassis on the driver's side of the dash, over
the steering column, with the removable cover plate facing the floor.
This position places the control shafts on the end of the case facing
the center of the car.

Locate the position of the mounting holes by means of the template
included in the package. Drill the holes, using a 3/8" drill, and scrape
the paint from around the holes on the engine side of the dash to insure
a good ground connection as there is no other ground connection for this
receiver.

Make sure that all tubes and the vibrator are pushed well down in their
sockets and that all the grid clips are properly in place on the top
caps of their respective tubes.

If a six-volt storage battery is available, check the receiver for
normal operation before permanently installing it on the car. The
antenna lead and control unit may be temporarily connected for this
test.

Insert the two receiver mounting studs in the back of the receiver case
with the "burred" threads nearest the receiver to make sure that these
studs do not enter the case far enough to cause damage to the receiver
parts.

Install the receiver, using the drilling template as a spacer between
the dash and the receiver case. Install the two shakeproof washers over
the chassis mounting studs. Then tighten the mounting nuts to insure
that the receiver case shall be thoroughly grounded to the dash.


=Antenna Lead--=

Attach the black antenna lead to the car antenna and plug the connector
on the antenna lead into the receiver chassis as shown in the
Installation Diagrams. Ground the pigtail of the antenna lead shield to
a convenient body bolt. Keep antenna lead out of engine compartment to
avoid possibility of ignition interference being picked up by the
lead-in.


=Speaker--=

See Instructions in speaker package.


=Remote Control Unit--=

See Instructions in remote control package.


CONTROL UNIT ADJUSTMENT

The volume control and station selector shafts are AUTOMATICALLY
adjusted as follows:

1. Insert control cables in their respective bushings on the case
(volume control is upper bushing when receiver is installed in the car),
until they seat themselves and then tighten the set screws.

2. Turn the station selector knob to the right (clockwise) until it
stops--then turn the knob counter-clockwise until it stops. The dial is
now logged.

3. Turn the volume control knob clockwise until the knob turns hard. The
volume control is now on full.


=Eliminating Motor Interference--=

Connect the ammeter condenser to the spring clip at the end of the wire
containing the fuse holder by means of the self-threading screw on the
side of the spring clip. Ground the other terminal of the condenser at
any convenient point.

Install the generator condenser on the generator side of the generator
cut-out as shown in the Diagram of Connections. DO NOT connect the
flexible lead to the field terminal of the generator.

Remove the center distributor lead and insert the distributor suppressor
in its place. Then plug the distributor lead into the suppressor.


=Adjusting Delco Syncro-Tuning--=

Turn the receiver on.

Tune-in a radio station which logs between 55 and 65 on the dial and
gives the radio a signal BARELY AUDIBLE in the speaker WITH the VOLUME
control FULL ON. A small snap button cap is located in the end of the
receiver case beside the antenna lead connection. Remove the snap button
cap by prying with a small screw driver.

By means of a small screw driver inserted in the hole which was covered
by the small cap, adjust the Delco Syncro-Tuning condenser unit for
maximum output in the speaker. Remaining on same station, readjust
station selector for maximum volume and readjust the Delco Syncro-Tuning
Condenser unit for maximum output. No further adjustment of this unit
will be necessary as the receiver is now adjusted for best operation
with your car antenna. Replace the snap button cap.




OPERATION


=To Turn On Receiver--=

Some control units have a small knob located below the center of the
dial. If your receiver is equipped with this type of control push this
small knob in as far as it will go. Other control units have a
combination on-off switch and volume control knob. To turn on this type
of control turn the knob clockwise until the switch clicks and the dial
is illuminated.


=Volume Control--=

Turning the volume control knob toward the right increases the output of
the receiver and turning it toward the left reduces the output.


=How To Tune The Receiver--=

Turn the volume control knob approximately half way to the right. Rotate
the station selector knob slowly until a station is heard. Tune this
station in until the minimum amount of background noise is heard.
Increase or decrease the volume to the desired level by adjusting the
volume control knob. Careful tuning will result in better tone quality
from all stations.

If the program being received is from a powerful local station local
interference may be practically eliminated by turning the sensitivity
control to the LOCAL position. You then will get the best possible
reproduction of that station's program.

=Sensitivity Control--=

The sensitivity control is located on the lower, left front corner of
the receiver case and when turned to the LOCAL position it decreases the
sensitivity of the receiver sufficiently to greatly reduce interference
from street cars, electric signs, X-Ray machines, electrical machinery,
power lines, etc. It will also eliminate interference from weak
stations.

When the control is turned to the DISTANCE position the receiver is
allowed to operate at maximum sensitivity.


=Tone Control--=

The tone control is located on the lower, right front corner of the
receiver case. This control is to be adjusted at the operator's will.
However, most experienced operators prefer to set it for maximum treble
response when the car is operated at high speeds.


=To Turn Off The Receiver--=

If the control head has a key knob in the center pull the knob out until
it clicks into the off position and the receiver ceases to operate. If
you wish to lock the receiver, pull the knob all the way out of the
control unit and carry it with you.

If you are using the type of control unit which has a combination on-off
switch and volume control knob turn the knob to the left until the
receiver ceases to operate.




SERVICE


Should your receiver fail to operate, first check the fuse located in
the fuse holder in the ammeter cable. If you wish to remove your tubes
and vibrator for test purposes, their location is indicated below.

Any further service work on your receiver should be referred to a
competent radio service station.

INSTALLING SERVICE DELCOTRON® GENERATOR

1. DISCONNECT GROUNDED CABLE FROM BATTERY.

2. If it is necessary to rotate the slip ring end frame to match the
unit being replaced, remove the thru bolts, separate frames just far
enough to rotate to desired position and replace thru bolts.

CAUTION: Separating the end frame too far causes the brushes to drop on
to the greased shaft. If this happens, remove end frame completely,
clean brushes with clean cloth, reassemble springs and brushes retaining
them in position with a pin (toothpick). Remove pin after frames are
reassembled.


WHEN INSTALLING DELCOTRON® GENERATOR WITH INTEGRAL REGULATOR, THE SLIP
RING END FRAME MOUNTING BRACKET IS NOT NEEDED.

3. When reusing the original fan, pulley and collar, tighten shaft nut
to 40 to 60 lb. ft. If torque wrench is not available, insert a 5/16"
hex wrench in end of shaft and tighten nut until the spring washer is
just flattened.

4. Install Delcotron® Generator and check belt tension, mounting bolt
tightness and make sure all electrical connections are clean and secure.

IMPORTANT: Never operate the Delcotron® Generator without being
connected to the battery. Never attempt to polarize the Delcotron®
Generator.
