label: Description (Brief)
content: A pentode with a 6-pin plastic base, top cap, domed glass envelope. Stamped: “Western Electric / Made in U.S.A. / 310A”. Indirectly heated cathode. Heater voltage: 10, AC or DC; heater current: 0.32 amperes; plate voltage: 135 or 180. "A voltage-amplifier, suppressor-grid pentode with indirectly heated cathode. This tube is intended primarily for use as an audio, or carrier and radio-frequency voltage amplifier, oscillator, or modulator. The connection for the suppressor grid has been brought out to an external terminal, thus making the tube more flexible in its applications."
