The vacuum tube, which occupies sann important part in almost every kind of radio appal':ltus,l and which has particularly contributed‘ to the successful use of “wired wire-I less,” was known'in various forms clur— A ing the‘ war, but its developments dur- { ing the few years of hostilities represents at least a decade under normal conditions.
