Development of inspection manual for reliable tubes

Reliable tubes is a subject that has received a lot of publicity in the electronics field during the last few years. Nobody will dispute that tube reliability is a “must” in our present and future defense weapons. The need for an Acceptance Inspection Manual — which outlines the inspection procedures for reliable tubes, is obvious. The Inspection Manual¹ that I am discussing this afternoon, was developed for the acceptance inspection of JAN Reliable Tubes.
