Raytheon 5D23/RK65 RF transmitting tetrode: maximum plate voltage 3000 V, grid1 -250 V, grid2 500 V; maximum plate current 250 mA, grid1 current 40 mA, grid2 current 80 mA per catalog table. Plate dissipation 215 W; RF drive 15 W, output 565 W. Direct capacitances grid-plate 0.42 pF, input 10 pF, output 5 pF. Thoriated-tungsten directly heated filament 5 V 14 A. Jumbo 4-pin base. Screen dissipation not specified, so remains null. No separate conventional parameter records added.

Source-dependent data

Operating conditions by source

Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.

No source-specific operating conditions are recorded.
