Wax nostalgic about and learn from the history of early electronics. See articles from Radio & Television News, published 1919-1959. All copyrights hereby acknowledged.

Sparton Models 526PS (RadioMuseum.org) - RF CafeMagazines usually provided at least a brief description on the circuit functionality for each of the radio models presented in schematic format. The April 1947 issue of Radio News published schematics and parts lists for six sets, including this for the Sparton Models 526, 526X, 526PS, but not a word about any of them accompanied it. The thumbnail image is from the RadioMuseum.org website. These are posted as part of my ongoing effort to make the information available to those who repair and/or restore vintage vacuum tube radio sets. Services like SAMS Photofact®, which began operation in 1946, is still an excellent source of the most detailed data available.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines.

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...
