Essay Commentary Many
of the early “Blues” were small devices, as Raytheon began improving the
technology for transistor encapsulation.
Shown above are examples of various small case styles, with a “standard”
CK721 shown in the center for comparison.
The three leftmost units were all developed for hearing aid use, which
was a primary market for Raytheon for many years, and which benefited from
small size. The CK782 is a “half-height”
hearing aid transistor shown next to the more common CK785. The CK726 is a fragile and elegant style,
made for a very short time. Only a
few examples are known to exist, all retrieved from hearing aids. The three rightmost units are general purpose transistors, all
in small case styles. Go
