Description
A9-404 etched on inside of tube. The 3W5000A3 is a water-cooled version of the air-cooled 3X2500A3. The 1953 and 1959 product sheets describe it as "a water-cooled, medium-mu transmitting triode with a maximum plate dissipation rating of 5000 watts. Relatively high power-output as an oscillator, amplifier or modulator may be obtained from this tube at low plate voltages. A single tube will deliver a radio frequency output of 7500 watts at 4000 volts at frequencies up to 110 Mc. This tube has a rugged, low-inductance cylindrical filament-stem structure, which readily becomes a part of a linear filament-tank circuit for VHF operation. The grid provides thorough shielding between the input and output circuits for grounded-grid applications and is conveniently terminated ina ring between the plate and filament terminals. The 3W5000A3 should be used where water cooling is preferred and for industrial applications or installations where reserve anode dissipation is desired. For use as radio frequency power amplifier/oscillator, plate modulated radio frequency amplifier, audio frequency power amplifier and modulator.
