RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

July 1936 Radio Craft Cover - RF Cafe[Table of Contents]

People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Radio-Craft was published from 1929 through 1953. All copyrights are hereby acknowledged. See all articles from Radio-Craft.

At least for now, I am going to only scan and post schematics & parts lists like this one featuring the General Electric Model N-60 6-Tube Auto Superheterodyne radio in graphical format, rather than run OCR on them to separate the textual content. There are still many people who restore and service these vintage radios, and often it can be difficult or impossible to find schematics and/or tuning information. I will keep a running list of all data sheets to facilitate a search.

General Electric Model N-60 6-Tube Auto Superheterodyne
Radio Service Data Sheet

(Maximum power output, 4 W.; tuning range, 530 to 1,650 kc.; iron-core antenna coil; provision for high- or low-capacity metal tubes; instrument-panel mountings for all popular cars; very complete filtering.)

The table of voltages for this receiver follows:

*Read with 250,000 ohm meter; **read across the filter choke. The plate. S.-G., and cathode voltages are all read to ground, while the heater readings are taken directly across the socket terminals. For aligning the I.F. stage, the lead from the signal generator should be connected to the stator or the first-detector section of the main tuning condenser, through a 0.05-mf. condenser. A ground connection must be made to the chassis from the generator. Short out the oscillator section of the condenser, and set the receiver volume control at maximum position, adjusting the output of the service oscillator so that it is not high enough to cause the A.V.C. action of the receiver to take place. Then set trimmers C10, C11, and C13 for highest output. Turn the set tuning condenser to full-open position and set the service oscillator for 1,650 kc. If a low-capacity antenna is to be used with the set, connect the antenna lead to the service oscillator through a 150 mmf. condenser, or through a 0.0015-mf. condenser if the antenna is of high capacity. Adjust trimmer CC for best output. Set the service oscillator to 1,400 kc. and turn the receiver tuning condenser carefully for best output, then set CA and CB for best output. After the receiver is installed in the car it is best to readjust trimmer CA to match the antenna used. Tune in a weak station around 1,200 kc. on the dial and with the volume control about three-fourths on, set CA for best results. The dial is set to the correct frequency calibration by turning a small screw on the back of the control head after the pilot lamp assembly has been removed. Be sure that the cover of the set is tightly fitted after it has been removed. It is sometimes necessary to remove paint and dirt particles that prevent a tight fit in order to stop ignition noise. The receiver is fitted with a universal control head which can be used on almost any car, by the use of the correct type of escutcheon plate.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 152 Radio Service Data Sheets as of November 14, 2016.
