Since 1910, the name "HICKOK" inscribed on elec- trical and electronic instruments has been the assur- ance of the finest and most dependable in electronic test equipment. For longer than there has been an "electronics" industry, HICKOK engineering has continually pioneered in the development of highest quality, versatile, reliable test and indicating instruments. From the days of Marconi's wireless, into the age of semiconductors, HICKOK has led the way in such 1910-1964 important development as: HICKOK • The first Dynamic Mutual Conductance Tube Tester , universally accepted as providing the standard test Recognized For Excellence of a vacuum tube .. HICKOK tube testers have been widely emulated -they have never been surpassed. For 54 Years • The friction·free, Taut-Band Meter-eliminating friction from pivots, jewels and hairsprings. • 250 0 Scale Meters . • Sub-miniature, ruggedized meters built to military specifications. • And now, in the Transistor Age-a full line of tran· sistor testing instruments featuring the same ease of operation, unmatched versatility, une xcelled reliability that have characterized HICKOK products for more than half a century. ,1~ ];~-'[ gu;4-eo ~,~zc. 3302 W . 8ROAD S T.
