What Edison is to electricity
De Forest is to radio
name De Forest is linked in-
X separably with radio progress and
achievement. Lee De Forest gave to
the world the vacuum tube that made
modern radio possible.
In the De Forest Tube today dealers
sell a tube that in every respect is
worthy of this great name. The De
Forest Tube is helping many merchants
build a greater tube business. You have
the same opportunity.
If you become an agent for De Forest
Tubes you have three important ad-
vantages :
I* Characteristics of De Forest
Tubes. These tubes are noted among
radio experts and amateurs alike for
their uniformity—their constantly uni-
form performance in both laboratory
and in the home set. Test after test is
made before any of them leave the fac-
tory. Thus you and your customers can
rely on De Forest Tubes to help repro-
duce the full volume and beauty of the
voice or music—to be remarkably non-
microphonic—to withstand overloads
of current without injury. De Forest
Tubes are interchangeable in all stand-
ard circuits and can be used as both
detectors and amplifiers in the same
circuit.
These are characteristics that make
purchasers of De Forest Tubes satis-
fied customers and also salesmen for the
dealer from whom they buy.
Z« The De Forest name. Veteran
radio fans in your community know
De Forest Tubes as standards of ex-
cellence.
3» Advertising. Set buyers and own-
ers throughout the country who do not
know the characteristics and superior
qualities of De Forest Tubes are being
educated through the medium of De
Forest advertising in national radio
magazines and in newspapers of radio
centers. This advertising will point the
way to De Forest agents and help to
make it still easier for merchants to
build a larger tube business.
There are only two types of De
Forest Tubes to carry—only two are
necessary, the DV-3 for dry batteries
and the DV-2 for storage batteries.
Both are shown on this page.
Write to us now, immediately upon
reading these words, for complete infor-
mation as to how you can become a
De Forest agent. If you are already a
De Forest agent, check your stock of
tubes so that you will be prepared for
the holiday buying season.
