Abstract:

The purpose of this project was to evaluate pyrolytic graphite grids. Several tubes were built to the same general geometry as the 4cw100,000E. The X2097U has a pyrolytic grid and screen. The number of grid bars was increased by 50 to improve cutoff characteristics. The stem was redesigned to improve thermal cycling stability. The X2097V in addition had a high density filament which increased perveance by 30. The tubes are physically interchangeable with the 4CW100,000E and in critical applications requiring high grid and screen dissipation and low drive voltage have superior performance.
