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.

General Motors Chevrolet No. 601574: In this receiver the antenna circuit is capacity coupled to the antenna system. This results in exceptionally high gain in the antenna stage and serves to compensate for the relative inefficiency of the undercar antennas required in the all-steel-top cars. An adjustment in the receiver permits alignment to the car antenna. Tube V1 functions as both R.F. and A.F. amplifier. To permit suppressor-less operation the battery circuit to the receiver is very carefully filtered. The reproducer mounts above the windshield. Master Chevrolet car rear wheels are equipped at the factory with anti-static fittings. Similar fittings for the front wheels are supplied with the radio set. The plug-in, full-wave, self-rectifying vibrator "B" unit is permanently connected for operation on negative-grounded battery supply. Because of space limitations in the header-type reproducer, the output transformer is built into the receiver chassis.

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.
