HISTORIC TRANSISTOR HOBBYIST SUPPLIES!
Supplies for the Transistor Historian and Kit Builder.
Only from the TransistorMuseum™
The CK718 is historically
important because it was the first transistor to be produced in large
quantities for commercial applications.
Raytheon introduced the CK718 in late 1952 to maintain its
leadership position with hearing aid manufacturers (first established with
Raytheon submini vacuum tubes).
The CK718 was produced only from 1952 through 1955 and represents a
unique and important milestone in the history of transistor technology. Your CK718 has been tested and will
produce a beautiful, clear tone when used in the classic code oscillator
circuit shown below (and in your insert).
