December 1947 Radio News
December 1947 Radio & Television News Cover - RF Cafe[Table of Contents]  These articles are scanned and OCRed from old editions of the Radio & Television News magazine. Here is a list of the Radio & Television News articles I have already posted. All copyrights are hereby acknowledged.

Farnsworth model EC-260 (radiomuseum.org) - RF CafeFarnsworth model EC-260 (SAMS Photofact) - RF CafeMagazines usually provided at least a brief description on the circuit functionality for each of the radio models presented in schematic format. The January 1947 issue of Radio News published schematics and parts lists for six sets, including this for the Farnsworth models EC-260, EK-262, EK-263, EK-264, and EK-265, but not a word about any of them accompanied it. One thumbnail image is the SAMS Photofact from an eBay auction, and the photo thumbnail 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.

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.
