Abstract :
Ninety per cent of the service interruptions of ENIAC at Aberdeen Proving Ground are caused by vacuum-tube failures. A 5-month tube surveillance program was conducted wherein faulty tubes were detected and replaced. How such tubes were tested and their histories gathered is described together with the preliminary findings.
