LIFE TESTS OF VACUUM TUBES UNDER SIMULATED CONDITIONS OF SHIPBOARD STORAGE OF GUIDED MISSILES,

Abstract

Nine tubes of each of four subminiature types (Type 5718, Type 5719, Type 5840, and Type 5899) were subjected to shock excitation at a fundamental frequency of 23 cycles per second with an amplitude of 0.11 inches. Various parameters and leakages were measured as well as microphonic noise. There is no evidence that any tube was seriously affected by this treatment and, on the average, the tubes were essentially unchanged by the 22,000 hours of vibration which they experienced.
