Emerson Model 507 Tabletop Radio (eBay image)

For many years I have scanned and posted schematics & parts lists like this one featuring the Emerson models 507, 509, 518, 522, 535 Chassis Model 120005. An image of the page is included which, depending on the issue, might include a schematic, parts list, and tuning and service information. If there is extensive text, I run OCR on the scanned page and place it on the page to aid search engines. In this case, the September 1947 edition of Radio News contained only the schematic and parts list. A lot of these radios can be purchased on eBay. The Radio Museum and Radio Attic websites have some additional information. In fact, the image to the left is from a recent sale there. There are still many people who restore and service these vintage radios, and often it can be difficult or impossible to find schematics and/or tuning information. A running list of all data sheets posted thus far is at the bottom of the page.

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 lady's voice announced "You've Got Mail" when a new message arrived...
