TUBE 6159 tube raytheonThe Raytheon 6159 (and its variants like the 6159A, 6159B, and ruggedized JAN-6159W) is a vintage beam power pentode vacuum tube designed primarily for VHF radio transmitters, RF power amplifiers, and mobile communications equipment - The 6159 is electrically identical to the legendary 6146 tube, with one crucial exception: its heater voltage.6146 Tube: Uses a standard 6.3V heater.6159 Tube: Uses a 26.5V heater (drawing 0.3 Amps).Because of this 26.5V filament requirement, it was heavily utilized in military, marine, and aircraft avionics systems that ran on 24V–28V DC electrical systems, as it allowed the heaters to run directly off the vehicle's electrical bus without heavy step-down transformers - Tube Type: Beam Power Pentode (Universal)Base Type: Octal (8-pin) with a top plate capFilament/Heater Voltage: 26.5V AC or DC (\(\pm \)10%)Filament Current: 0.3 A (300 mA)Maximum Plate Voltage: Up to 750V DCMaximum Screen Voltage: 250V DCMax CW Power Input: 90 Watts (up to 60 MHz) / 60 Watts (at 175 MHz)
