These are the schematics and parts list for the vintage Arvin vacuum tube radio model 140P, as it appeared in the November 1947 issue of Radio News magazine. I scan and post these for the benefit of hobbyists and historians seeking such information. As time goes by, there is less and less likelihood that records of these relics from yesteryear's archives will be made available. The thumbnail image of an Arvin Model 140P is from a Chinese website - the only example I could find. As with all historical information, it takes someone with a personal interest in preserving the memories in order to fulfill the mission, and I am glad to be a small part of that cadre. A very large list of Radio Service Data Sheets and Schematics and Parts Lists like this one is given at the bottom of the page.

Arvin Radio: A Brief Overview and Historical Context

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.

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.

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.

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...
