Two tubes were assembled and one given initial tests and a life test during the past period. The life test was possibly influenced by the lack of several proper parts in the tube which was constructed as a calculated risk. The life test did not run to the specified minimum time and indicated that greater reservoir capacity was necessary. Construction features of the next tubes in the series are detailed and discussed.
