Here's a PDF image scan of the historic Sylvania products booklet, 28 Uses for Junction Transistors. This little booklet, from 1955, introduced amateurs and hobbyists to the famous 2N35, 2N34, and 2N68 junction transistors. It is hard for us today to appreciate how revolutionary was the introduction of the transistor to the hobby world.

|Simple Crystal Diode
Circuits is an undated publication from Sylvania Electric
Products. This is a 34-page booklet that contains some simple
but rather advanced introductory circuits. Examples are:
peak-to-peak television voltmeter probe, low frequency multiplier,
FM-TV discriminator, bridged T-phase modulator, and germanium triode
power supply; 40 projects in all.

Shortcuts for Hobbyists: 24 Simplified Crystal Diode Applications
for the Home Hobbyists, Experimenter and Model Maker is a
1951 publication presenting germanium diode projects using 1N34,
1N55, and 1N56 components. Projects include timer, polarity
checker, AC measurement adapter, inductive-kick quencher, charger,
relay, door chime, photocell, crystal radio, metronome, power
supply, and others.

|In 1952, Sylvania published a little
Crystal Diode Circuit Kinks: More New Uses for Germanium Diodes.
The little 36-page booklet is filled with simple
circuits using 1N34, 1N35, 1N54, 1N56, and 1N58 germanium diodes.
Some of the published circuits are of more than historical interest.
They could be put to ready use on my workbench today!

|Here is the Sylvania booklet,
40 Uses for Germanium Diodes. This may have preceded the
above titles although the booklet itself carries no date anywhere.
The circuits described in this publication are not your ordinary
hobby-demonstration circuits. They include schematics for such
things as "Compact Series-Shunt Impulse Noise Limiter," "Low-Voltage
Bias Supply," and an "External Modulator for Signal Generators."

Transistor Circuit Handbook for the Hobbyist: 30 Useful
Battery-Powered Transistor Circuits, published in 1960, has
30 projects developed by Sylvania Semiconductor Applications
Engineering Group along with United Engineers, Inc. Projects
include the usual crystal receiver, audio amp, and model train horn
along with novel items like a transistor beta checker, grid dip
meter, theremin, modulator, and phase inverter.

|Raytheon got into the act too, introducing their transistors, especially the
CK722, to the hobbyist market with the publication,
Raytheon Transistor Applications, More than 50 Practical Circuits using Raytheon
CK722 Transistors. This 120 page document is an 8.8 MB download.
The booklet doesn't have a publication date but I believe this is from 1955.

|Whereas the first Raytheon publication was mostly a collection of reprints
from electronic magazines their second effort in 1957 was a much more considered
and deliberate text,
Raytheon Transistor Applications Volume II. As it says
on the cover, "All New Circuits with complete how-to-do-it
instructions." Volume II makes it apparent that the first
volume was just thrown together. For instance, the first 17
pages of Volume II cover transistor basics and a section on
Practical Circuit Design with subsections on Amplifiers,
Breadboarding & Bias Measurement, Interstage Coupling, DC
Stabilization, Distortion, Oscillators, Transistor Installation,
Etched Circuit Boards, Testing Transistors, and Power Supplies for
transistor circuits. It also uses other transistors
besides the CK722.

|Here is a Raytheon reprint of an April
1952, article by John A. Doremus of Motorola originally appearing in the
Radio-Electronic Engineering section of Radio & Electronic News.
The article, "Point-Contact
and Junction Transistors," is an introductory piece presenting the
physics and potential of the new devices. Doremus predicts a
bright future for the little components now that "five manufacturers are
already 'in the business.' These are Western Electric, General Electric, Raytheon,
Sylvania, and RCA." In the reprint, Raytheon added
data sheets for the CK721 and CK722 transistors.

|Here is a marvelous little publication on
the brand new technology of
Tunnel Diodes. Published by General Electric Research
Laboratory in November, 1959, this concise 24-page booklet carried
monographs by Dr. Malcolm H. Hebb, Dr. Jerome J. Tiemann, and H. B.
Fancher describing the quantum physics behind the tunnel diode along
with applications for this technology. Many thanks go to Dave
Schoepf, W2GHZ, for making this document available.

|This 2nd edition of the
GE Transistor Manual:
Circuits, Applications, Specifications is a treasure of
detail on the early GE transistors. It begins with an
introduction to semiconductor physics and follows with basic circuit
components that are well explained. It proceeds with detail
specs on the individual transistors including form-factor diagrams
of even the pinched-top devices. Finally, it has circuit
diagrams for projects such as a vest pocket radio, amplifiers,
flasher, flip-flop, phonograph amplifiers, pre-amp, power supply,

|This tiny undated 8-page document from General Electric is clearly from the earliest introduction of the 2N107 transistor: Type 2N107 TRANSISTOR CIRCUITS For EXPERIMENTERS · AMATEURS. The publication shows six very basic circuits, although one, the "TV Antenna Orientation Meter" is interesting in that it connects to the TV chassis ground and the picture tube grid in order to help the experimenter find their TV stations! Some of the diagram labels are hand-written.|
|This is the one-page specification sheet for General Electric's 2N170 NPN junction transistor. The listing includes an example circuit configuration for using the transistor as an amplifier along with physical outlines & dimensions of the transistor in a pinched-top form factor.|
