• The 845 power triode is a radio transmitting vacuum tube which can also be used as an audio amplifier and modulation tube.
• Typically, the plate is machined from solid graphite in order to accommodate high power dissipation (up to 100 watts) and voltage.
• The gold plating base and feet make better connecting and it has a bayonet mount which can screw up like lightbulbs. This audio power triode has an anode dissipation of 75 Watts and operates with 1250 Volts on the anode.
• The thoriated tungsten filament is powered at 10 Volts and 3.25 Amps
• It is direct heated thoriated tungsten cathode triode which applied in class A1,Ab1 power amplification.
