April 1947 Radio News
[Table of Contents]
Wax nostalgic about and learn from the history of early electronics.

Television News, published 1919 - 1959. All copyrights hereby acknowledged.

Magazines 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 Radiola
Models 61-6, 61-7, 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. 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 220 Radio Service Data Sheets as of
February 2, 2018.
