Applicability of the Spark Coil Transformer in Determining the Condition of Vacuum Tubes

Abstract

The object of this investigation was to ascertain the efficacy of the "Spark Coil Transformer" for determining the condition of vacuum tubes. With the aid of this device, a rapid shelf check of tube stock can be made, thus preventing an accumulation of defective materials, and permitting of the replacement of defective materials by the manufacturer wherever a tube life guarantee prevails.
