Report on Vibration Test of Type 38064 Vacuum Tubes

Abstract

The vacuum tubes under test were mounted rigidly in a vertical position on a horizontal table and subjected to simple harmonic motion with an amplitude of 0.04 inch (total travel 0.08 inch) and over a frequency range of 25 to 34.5 cycles per second. The tubes were again tested in the above manner, after being rotated 90 about a vertical axis. The electrical disturbance set up within the tube was measured in both instances linear amplifier. In addition, the wave form of the voltage disturbance was viewed by a cathode ray oscillograph placed in the amplifier output circuit.
