Part of the reason
there are not as many (as a percentage) of us do-it-yourselfers and
fix-it-yourselfers these days as there was at the time this Radio-Electronics
magazine hit the news stands in 1961, it that a diminishingly small amount of
products are repairable by someone without special tools and/or special
knowledge. Some would say the reason for a majority of products that cannot be
serviced is because of the diminishing number of people having any interest in
building or fixing stuff. A similar argument is made about clothing, prepared
food, and other common items. Part of the explanation is the availability of
cheap products made by cheap overseas labor. For whatever the reason,
electronics service shops are quite rare these days. Howard Sams saw a need for
high quality troubleshooting and alignment documentation for services shops -
and filled it. Having entered the electronics realm in the 1970s, I remember
PhotoFacts being the go-to source of schematics for radios, TVs, phonographs,
and other household entertainment products.
