Description

The R59 series tubes are widely used in theater sound projection equipment. This medium sized tube has long been prominent in 35 MM semi- portable systems. Its rugged dependability makes it exceptionally adartable to "A" type sensitive to infra-red and “B” type sensitive to blue. The blue sensitive Visitron tubes have a high response to blue radiation and insignificant response to red radiation. This tube will prove advan- This variant uses the S1 cathode surface described by the family datasheet. The non-V variant has published gas amplification in the family table.
