Triode, Dual, HF
Miniature, medium-mu triode suitable for use in a wide variety of general purpose applications. It is especially useful as a local oscillator in high-frequency and very-high-frequency receiver circuits.
Metal sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.
Miniature tube which contains a sharp-cutoff pentode and a medium-mu triode. Each section has a separate cathode and is electrically independent.
DC-AC heating twin triode
Power amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and in high fidelity amplifiers.
Power pentode for output stages of high fidelity audio-amplifiers and radio receivers
Sharp-cutoff pentode of the 9-pin miniature type intended for use as an audio amplifier in applications requiring reduced microphonics, leakage noise, and hum.
Pentode intended for use as A.F. amplifier.
Triode-pentode designed primarily for high fidelity audio applications. The pentode section is particularly suited to preamplifier service while the triode section is intended for use as a phase inverter.
Miniature beam pentode primarily designed for use in the audio-frequency power-output stage of radio receivers. The tube features high power sensitivity and high efficiency at relatively low plate and screen voltages
Miniature half-wave rectifier for use in line-operated equipment having series-connected heaters. The heater is tapped to permit operation of a panel lamp.
Beam power tube, 9 pin miniature type, for high-fidelity audio-amplifier applications
Medium-mu twin triode 9-pin miniature type, intended for applications where dependable performance under shock and vibration is paramount. The 5814A is a "premium" version of the 12AU7.
Miniature high-mu twin triode each section of which as an individual cathode connection suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, andindustrial-control circuits where high voltage gain is desired.
Miniature, medium-mu, twin triode primarily designed for service in computer applications. Each triode section features a high zero-bias plate current, a sharp-cutoff characteristic, and a separate cathode connection.
Subminiature medium-mu twin triode for use in general purpose amplifier applications. Each section has an individual cathode and is electrically independent.
This full-wave, high-vacuum rectifier is specifically designed for aircraft, military, and industrial applications where freedom from early failures, long service life, and uniform operating characteristics are extremely important.
Tube having high efficiency and high power sensitivity for use in mobile and stationary equipment. It is rated as an af power amplifier and modulator, a linear rf power amplifier, and a Class C rf power amplifier and oscillator.
The 5881 is the electrical equivalent to types 6L6 and 6L6GC except that the plate and screen dissipation ratings have been increased approximately 20 percent.
