[Transcriber's Note: This ebook contains two manuals by Delco: Delco Radio Owner's Manual Model 633 and Delcotron Generator Installation. They are separated by a divider.

In the list on pages 10 and 11 of Delco Radio Owner's Manual Model 633, the second station line for Tulsa (which is CFRB 690) has been removed, as it is believed to be an accidental reprinting of the following station line. Redundant headers and (foot)notes on these pages have also been removed.]



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:

Part No.

1 Receiver Unit, complete with tubes

1 Speaker Unit (less Adapter) 1210934

1 Combined Drilling Template and Radio—Dash Spacer

2 Chassis Mounting studs, 1/4—20 x 2-1/2 1207562

2 Chassis Mounting Shakeproof Washers 1208565

2 Chassis Mounting Nuts, 1/4—20 120375

1 Antenna Lead 1209622

1 Distributor Suppressor 1207818

1 Generator Condenser 1849014

1 Ammeter Condenser 1209333



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.
