- CK722 abstract "The CK722 was the first low-cost junction transistor available to the general public. It was a PNP germanium small signal unit. Developed by Norman Krim, it was introduced by Raytheon in early 1953 for $7.60 each; the price was reduced to $3.50 in late 1954 and to $0.99 in 1956. Norm Krim selected Radio Shack to sell the CK721 and CK722 through their catalog. Krim had a long-standing personal and business relationship with Radio Shack. The CK722s were selected \"fall out\" from the Raytheon's premium-priced CK721 (which are fallouts from CK718 hearing-aid transistors). Raytheon actively encouraged hobbyist with design contest and advertisements.In the 1950s and 1960s, hundreds of hobbyist electronics projects based around the CK722 transistor were published in popular books and magazines. Raytheon also participated in expanding the role of the CK721/CK722 as a hobbyist electronics device by publishing \"Transistor Applications\" and \"Transistor Applications- Volume 2\" during the mid-1950s.".
