These are the covers of the last four editions of the GE Transistor Manual.  The Fourth Edition, upper left, was published in 1959 and had 226 pages.  The Fifth Edition, upper right, was published in 1960 and had 329 pages.  The Sixth Edition, lower left, was published in 1962 and had 455 pages.  The Seventh and last edition was published in 1964 with 659 pages.  Dwight Jones contributed audio and Hi-Fi circuits to each of these volumes.  Also, according to Dwight, the Seventh edition was so thick that GE published a special edition on extra thin ”plasticized” paper which was approximately half the thickness of the regular version.

Do you have any specific comments about the GE Transistor Manuals?

 

As I mentioned, I started to work on these with the Fourth Edition, which came out in 1959.  I was a member of the Transistor Applications Group in Syracuse. This was in the SPD (Semiconductor Products Department). Hugh Lowry was the manager of this Applications group.  You can see a list of our names on the first page of so of these manuals.  Each of us was responsible for a certain part of the manual, depending on our assignments.  I’ve already told you that my expertise was in audio and HiFi, so those were the sections I worked on.  I designed all of those circuits and then had a technician build them so I could review the performance.  Over the years I heard from quite a few engineers and experimenters who really used these volumes in their work or hobbies to design and build transistor circuits. 

 

In addition to your work with early transistor HiFi, are there any other semiconductor assignments you had which you’d like to mention?

 

In the late 1950s, GE developed a new semiconductor device called the Silicon Controlled Rectifier (SCR).  This device was very useful in controlling voltage, as a switching controller, and became a very successful product for GE.
