 Hersteller: Cleartron Vacuum Tube Co., 28 West 44th Street, New York, USA. Als besondere Röhre erwähnt Tyne die Emerson Multivalve, eine 3-fach Röhre, die 1927 von Emerson Radval Corporation inseriert worden sein soll. Interessant ist zu wissen, dass Emerson 25 West 43th Street und Cleartron 28 West 44th Street lagen, sozusagen "Rücken an Rücken"
