Until solid state electronics had supplanted the majority of vacuum tube type televisions and radios, portable tube testers were essential equipment to successful, efficient troubleshooting and repair in businesses and people's homes. Yep, believe it or not the stories told about doctors and electronics repairmen visiting homes are not just fables. I remember as recently as the 1960s having our family doctor make house calls when I or one of my fours sisters got sick. Both doctors and TV servicemen ceased the practice at about the same time - probably the result of a Brotherhood of Electronics Technicians and General Practitioners collective bargaining agreement ;-) Many column inches of editorials, articles, comics, and letters to the editor were devoted to the trials and tribulations of in-home servicemen and the experiences they had dealing with customers. Do a search of television radio service on RF Cafe and you'll find lots of examples from my collection of vintage electronics magazines.
This advertisement for B&K Manufacturing's line of vacuum tube testers is from a 1960 issue of Electronics World. I still have a B&K Dyna-Quik Model 650 vacuum tube tester (top photo in ad below) given to me in the 1980s by über engineer Jim Wilson when I worked as a technician at Westinghouse Electric Corporation in Annapolis, Maryland. The $179.95 cost in April 1960 is equivalent to $1,537.13 today (2018), per the BLS Inflation Calculator.
