The purpose of this investigation is threefold. First, to make static tests on subminiature tubes, collecting as much data as possible on their behavior at different values of heater voltage and at different values of plate voltage; and to compare uniformity of the same type tube made by two different manufacturers. Second, to make dynamic tests on the same tubes in a circuit which simulates their use in an actual amplifier. The purpose of these tests is to determine tube life, or changes in tube characteristics, under normal load and overload conditions. Third, an attempt to correlate the results of the static tests with the results of the dynamic tests and discover some method by which static testing may be used to accurately predict which tubes may fail under overload; or to prove that no simple criterion exists for such prediction.
