CK722 PACKAGING THROUGH THE YEARS |

The
CK722 was sold in at least four different cardboard packages. The top package shown in this photo is the
earliest, dating from early 1953. As
you can see, this is really a vacuum tube package, with the CK722 id stamped
on the end flap. Presumably, Raytheon
was able to quickly implement this packaging, because of the large volume of
Raytheon tubes manufactured in the same timeframe. In the photo, the topmost “foldover” matchbook style package
was the second type to be used. (Note the CK722 id in a banner type logo with
the word “transistor” next to the Raytheon logo). I have seen only black CK722s in this type of package. The third package from the top is the most
common in my experience, used with both blue and silver CK722s. Finally, the bottom package, using a
plastic bubble, was used only for silver CK722s. |
