The original triode. Direct from the manufacturer.
\nWhat if the best sound was achieved decades ago? In 1938, Western Electric manufactured the first type 300B electron tube. It was a breakthrough power triode, but in those days it hummed away from behind a curtain in early Hollywood sound systems. The same things that served moviegoers back then\u2014low noise, ultra-long life, sonic purity and warmth\u2014made it a standout tube for music lovers and vintage audio collectors as the years passed. Deep into the age of the transistor, communities around the world in search of true, original, high-fidelity sound rediscovered the 300B and its exceptional performance. New amplifier designs brought the tube front and center, its customary yellow lettering on proud display.<\/p>\n
Sometimes, the old ways are the best
\nToday, the 300B is manufactured at the Rossville Works. Our new factory home was custom-built to master the dozens of individual demands of tube making, from sealing the iconic glass bulb to the complex metallurgic processes within. We\u2019ve modernized the production line here and there to establish forward momentum at a company with 150 years of history. Western Electric believes twenty-first century listeners deserve twenty-first century manufacturing standards.<\/p>\n
Balanced, Powerful, Refined
\nThe WE 300B sound is balanced, powerful and refined with quality bass from the lowest frequencies through the upper bass. The midrange above is a thing of beauty; dulcet tones, seductive vocals, instruments of all types dimensional and present, all heightening the participatory elements of music.<\/p>\n
Burnished and Beautifully Seductive
\nHigh frequencies are at once transparent, lovely, sweet, burnished and beautifully seductive. The air and space between performers are extraordinary, performers appear on a quiet and focused soundstage whose width and depth are masterfully rendered. You don\u2019t have to search to find the sweet spot with a WE 300B amplifier, it\u2019s all around you.<\/p>\n
Find out what tube aficionados all over the globe know, the WE 300B is the most natural, elegant and emotive triode anywhere in the known universe.<\/p>\n
SPECIFICATIONS<\/p>\n
Classification
\nModerate power, filamentary triodes for Class-A service.<\/p>\n
Application
\nAudio-frequency amplifier in positions where power outputs of approximately ten watts or less are required at relatively low plate voltages.<\/p>\n
Dimensions
\nDimensions, outline diagrams of the tubes and bases, and the arrangement of electrode connections to the base terminals are shown in Figures 1 and 2.<\/p>\n
Base and Mounting
\nThese vacuum tubes employ medium, four-pin thrust type bases suitable for use in Western Electric 143B or similar sockets. The 300B tube has the bayonet pin so located that it may also be mounted in a Western Electric 100M, 115B, or similar socket.<\/p>\n
The tubes may be mounted in either a vertical or horizontal position. If mounted In a horizontal position, the plane of the filament, which is indicated In Figure 2, should be vertical.<\/p>\n
Average Direct Interelectrode Capacitances
\nGrid to plate 15 \u00b5\u00b5f.
\nGrid to filament 9 \u00b5\u00b5f.
\nPlate to filament 4.3 \u00b5\u00b5f.<\/p>\n
Filament Rating
\nFilament voltage 5.0 volts, a.c. or d.c.
\nNominal filament current 1.2 amperes<\/p>\n
The filaments of these tubes are designed to operate on a voltage basis and should be operated at as near the rated voltage as possible. When alternating current is used for heating the filament, the grid and plate returns should be connected to a center tap on the secondary of the filament transformer.<\/p>\n
