The ''' | The '''DuMont 5XP''' is a family of flat-faced 5" CRTs produced from 1948 onward. A 5XP-A series with tighter tolerances followed in 1953,and a 5XP-B range in 1954 that had an aluminized screen for higher brightness. | ||
Compared to earlier tubes, they had improved vertical deflection sensitivity, which was achieved by decreasing vertical deflection plate width and reducing spacing between the plates, at the cost of limiting vertical scan Tomas little as 1.25" at 20 kV acceleration. | |||
Maximum acceleration voltage was 25.5 kV. | |||
They are used in early models of the [[513]] and [[517]], before Tektronix switched these to Tek-made CRTs. | They are used in early models of the [[513]] and [[517]], before Tektronix switched these to Tek-made CRTs. | ||
