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
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.
