BUCKET OF TRANSISTORS

 

 

This truly amazing photo was on the cover of the March 1953 Electronics magazine.  It shows the temperature cycling racks that were used by Raytheon for “testing and aging” the CK718/721/722 germanium junction transistors at the 55 Chapel St., Newton Massachusetts manufacturing facility. According to Frank Dukat, the Raytheon Transistor Applications Product Manager at this time, “ the transistors were regularly inventoried before and after these tests.  The count always showed none missing.  However, one day, the racks were up for maintenance and many, many transistors were found at the bottom of the oven!!” - I’D JUST LIKE TO FIND THAT BUCKET IN THE PHOTO WHICH IS FILLED TO THE BRIM WITH CK TRANSISTORS!!
