General Electric C-62 Tabletop Radio - RF CafeThe General Electric C-62 radio was (is) a battery-operated tabletop model. No photos of actual radios could be found online, but the thumbnail to the left of an advertisement appears on the RadioMuseum.org website. Two 67.5 V "B" batteries provided power. You would be forgiven for believing such batteries are no longer available today since nowadays the most familiar types are 1.2 V and 1.5 V "A," "C," and "D" cells, and the 9 V "transistor radio" battery - which should be renamed the "smoke detector battery" since few pocket-type transistor radios remain. Less prominent in the retail venue but ubiquitous in electronics and power tools are the Nx3.7 V Li-Po batteries. If you want to get a good idea of the vast selection of battery shapes and voltages available, visit a website like Battery Central Mall. BTW, if you buy batteries online, please do so via this Amazon.com link so that I earn a commission (does not affect your price).

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.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


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...
