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.
Here are a few PhotoFact ads from vintage electronics magazine:
