Notes Developed around the new subminiature tubes in 1942 its production would not commence due to stop of commercial production. War work prevailed. But Government priorities were granted in 1943 for the production even in wartime ! The reason was that there were about ten million people hard of hearing in the country who were unable to serve in the military. But they were able to work in war production facilities if they had a hearing aid.
