B & K Precision
founded 1948
B & K was founded in 1948 in a garage by Chicago entrepreneurs Philip Ban and Carl Korn. They made maintenance parts for early televisions and opened Central Television Service Company. By 1951, they had become B & K Precision Corporation.
In 1961, B & K became a subsidiary of Dynascan. Throughout the 50s and early 60s, B&K Electronics, along with many other small electronics companies, joined forces to form Dynascan Corporation. In 1963, Dynascan engineers developed the world’s first citizens band (CB) radio, the Sidewinder, which was shortly followed by the Cobra. With widespread acceptance of CBs in the marketplace, the Cobra name caught on with consumers and eventually evolved into the symbol and brand name for this signature product..
