Arvin car radio receiver, power supply, and speaker.

Arvin, a subsidiary of Noblitt−Sparks Industries, was a brand of car radios and audio equipment that was popular in the 20th century. Founded in the 1930s, Arvin quickly established itself as a leader in the field of automotive sound systems. Known for its quality and reliability, Arvin's products were widely used by American consumers and became synonymous with in-car entertainment. At a time when radio was still a relatively new technology, Arvin's car radios stood out for their compact size and ease of use. They were well-designed and offered a range of features, including AM/FM tuning, volume control, and push-button tuning. Arvin also offered a range of other audio products, including home radios and portable speakers, that were well-received by consumers. This schematic for the Arvin−Ford 17−A Automotive Radio was published in the June 1935 issue of Radio−Craft magazine. The image to the left is representative of an Arvin car radio of the era.

Remarkable improvements in car sets are indicated these diagrams of the new automotive radio receivers shown on the preceding page.

Arvin-Ford 17-A: A 2-way plug switch provides extreme sensitivity for country driving, and lowered sensitivity and reduced noise level for city driving. Tuning condensers and tuning mechanism float on rubber to prevent car vibration from detuning the set. Filter condensers are hermetically sealed. Noise-filter circuits are built into the set. The vibrator "B" unit is of the non-synchronous type; a type 84 tube supplies the required rectification. Field current for the dynamic reproducer is obtained by connecting the field coil directly in shunt with the car battery. A stage of tuned R.F. amplification ahead of the first-detector eliminates image frequency response. The oscillator circuit is tuned by a shaped-plate condenser.

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 227 Radio Service Data Sheets as of December 28, 2020.

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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
