Radio today (Jan-Mar 1939)

46 Years of KNOWING HOW! In '93 when the world was gasping at the sights of the Chicago World's Fair, the Fred Goat Company was founded to pioneer important developments in cooperation with the rnetal working and special machinery industries. For nearly half a century, Goat has collaborated with engineers in a continuous pioneering service. Notable contributions were made to radio, including the now famous form-fitting tube shields. 1939 finds Goat the leading independent supplier of tube parts and tube shields. This is the TENTH year of Goat service to the radio industry. Besides cooperating with leading radio engineers, Goat is constantly pioneering improvements in shielding to promote better reception. In fact, the form-fitting feature of the Goat shield has contributed greatly toward the compactness of present day receivers. STANDARD and SPECIAL TYPES of SHIELDS for Home sets . . .
