Arvin Car Radio - RF CafeThis is another Radio Service Data Sheet that appeared in the May 1936 edition of Radio-Craft magazine. I post this schematic and functional description of the Arvin Model 35, 8-Tube Car-Radio Receiver manufacturers' publications for the benefit of hobbyists and archivists who might be searching for such information either in a effort to restore a radio to working condition, or to collect archival information. A WWW search for an Arvin Model 35 Car Radio did not turn up any results, but I did see the unknown model shown here on an expired eBay auction. It has a speaker front that looks like the Model 35. Installing and servicing the earlier heavy, bulky car radios was the source of many electronic-themed comics and articles. Some of the very earliest two-way radio sets (of which this is not) had massive transformers, needed to generate power for the transmitter, in separately mounted power supplies.

Arvin Model 35, 8-Tube Car-Radio Receiver

 - RF Cafe(Push-pull output; tone control: highly filtered against noise.)

These receivers are designed for ease of motor noise elimination. In rare cases certain cars may be especially hard to work with. In such cases, the Service Man may solder a 3 1/2 in. length of shielding to the underside of the condenser pulley mounting bracket, directly between the 2 6/32 screws which hold the Bowden-wire housing clamp onto this bracket. The other end of this shielding is then hung over the edge of the chassis case on top of the copper-case ground shim, so that when the cover is put on, the condenser pulley assembly is bonded to the outer case. The usual suppressors will then be found to eliminate all trace of noise.

It will be noted that there are terminals provided for use of an external speaker, which may be of the electro-magnetic or permanent-magnet dynamic type.

A table is herewith given of voltage measurements as taken with a 1,000 ohms-per-volt meter;

C.-G. voltages are measured with a V.-T. volt-meter. Plus or minus 20 per cent is acceptable on all voltages.


Arvin Radio: A Brief Overview and Historical Context

Arvin, brand 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.

Over the years, Arvin continued to evolve and innovate, adding new features and keeping up with changing trends and technologies. The company's products were widely available through a network of dealers and distributors, and they were often featured in advertising and promotions aimed at the American public.

Despite its early success and popularity, however, Arvin faced increased competition in the latter half of the 20th century. New technologies, such as cassette tapes and CD players, emerged and changed the way people listened to music in their cars. Additionally, foreign brands entered the market and offered products that were more advanced and less expensive than Arvin's offerings.

Despite these challenges, Arvin remained a significant player in the automotive audio market for many years. However, as the company faced financial difficulties in the latter part of the 20th century, it was eventually acquired by another company and the Arvin brand was discontinued.

Today, Arvin is remembered as a pioneering brand in the field of automotive audio. Despite the challenges it faced and its eventual decline, its legacy continues to influence the industry and is still celebrated by many people who remember its products and the role they played in shaping the American automotive landscape.

In conclusion, Arvin was a popular brand of car radios and audio equipment that was known for its quality and reliability. Although the company faced increased competition and eventually declined, its legacy continues to influence the industry and is remembered by many people today as a pioneer in the field of automotive audio.

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...
