December 1958 Popular Electronics
Wax nostalgic about and learn from the history of early electronics. See articles

A few days ago I posted
an old ad for Radio Shack and mentioned the tube testers that used to be in
the stores for customers to use free of charge. Of course they also had a nice stock
of replacement tubes for you to buy if needed. This advertisement for a typical
vacuum tube tester by Century Electronics appeared in the December 1958 edition
of Popular Electronics magazine. According to the U.S. Bureau of Labor
inflation calculator, that $134.50 price in 1958 (the year I was
born BTW) would be equivalent to $1,287.24 in 2021 money - not too bad really if
it were still made in the USA as it was then.

It's the easiest business to get into . . .requires no experience, little time and
A basic principle for making money is to have something work for you, rather

source of income and can be operated from home. All you do is make calls once a

What Is the Self-Service Tube Testing Business?
The self-service tube testing business is a take-off on the highly profitable
vending machine business . . .but with several decided advantages. Larger unit sales
and greater flexibility in operation. You place testers and tube stock in stores
on consignment - the store location contributes floor space for the self-service
tube tester - store patrons are offered the use of the tube tester free - they in
turn buy their replacement tubes from stock in the tester. The store pays you for
all the tubes sold less his commission. Each tester placed can net up to $1000 a
year for you.
