Bendix TE-52 / 6889 genuine BEAM POWER amplifier, not an ordinary pentode, for high-voltage regulator and high-perveance pulse service in rugged aircraft, military and industrial systems. Heater 6.3 V 1.20 A, warm-up about 45 s; six-pin short intermediate-shell octal base with separate top-cap plate connection. Absolute DC maximum plate voltage 3000 V, screen voltage 850 V, plate dissipation 30 W, screen dissipation 3.5 W, cathode current 125 mA. Separate peak cathode limits: 250 mA instantaneous peak for continuous sine wave, conditional pulse maximum 4.5 A subject to duty-factor curves. Production-test typical gm 5400 µmhos (0.0054 S), allowable range 4500–6300 µmhos, test conditions not assumed as universal operating characteristics. Heater-to-cathode max ±450 V, bulb-temperature ceiling 300°C; maximum pulse plate current changes with duty factor and shall not be promoted as unrestricted DC current.
