Radio Service Data Sheet
June 1930 Radio-Craft

June 1930 Radio-Craft [Table of Contents] Wax nostalgic about and learn from the history of early electronics. See articles from Radio-Craft, published 1929 - 1953. All copyrights are hereby acknowledged.

These four Radiola superheterodynes use the same 6-tube catacomb, the first of this type put on the market by the Radio Corporation of America; differences lie in the mechanical arrangement of the units outside the catacomb, and in the electrical and artistic design. The "812," to which most of this material specially applies, is an entirely self-contained semi-portable table cabinet set with a battery compartment at each end. The A.F. output is obtained at a jack; a plug-operated switch changes the circuit from one A.F. to two. Another switch controls the "A" circuit. There is a master rheostat ("Battery Setting"), R3 in the diagram on this page, and also a vernier rheostat ("Volume Control") R2; the latter controls I.F. amplifier V3.

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.
