As I have noted before, Sams PhotoFacts were the indispensible gold standard for commercial electronics service documentation from the 1940's through maybe the 1980's. After that, there was not nearly as much of a demand for electronics servicing because most electronic products in the consumer market were fully transistorized and had a high level of integrated circuit (IC) components, and multi-layer printed circuit boards (PCB's). That made serviceability more difficult for both professionals and DIY repairmen. Steep price decreases and very rapid evolution of features resulted in most people opting to throw away broken radios, televisions, phonographs, etc., rather than pay to repair them. The death knell of serviceability was when fly speck size surface mount components dominated PCB assemblies. Sams PhotoFacts were for the era when vacuum tubes (and even transistors and IC's) were plugged into sockets and point-to-point chassis wiring was the method du jour.

About RF Cafe

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...
