Abstract :
This is a review of life test records of over 50,000 tubes which were tested for 500 hours, and over 4,000 tubes which were tested for 10,000 hours. The basic characteristics of filamentary subminiature tubes are also discussed with respect to their suitability for applications other than hearing aid and communications equipment.
