Power - TV Horizontal Output (sweep) ·BeamPower

17AV5GA

An octal-base beam-power pentode intended for television horizontal-deflection amplifier service. Equipped with a 16.8-volt, 450-milliampere controlled-warm-up heater, it combines high-voltage pulse tolerance with efficient output characteristics and an 11-watt plate-dissipation rating for color television sweep circuits.
