The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
Miniature triode designed for use as a grounded-grid radio-frequency amplifier, frequency converter, or oscillator at frequencies below approximately 300 megacycles.
Triode using the miniature construction. Its low capacitance and high ratio of plate current to transconductance allow use as a high frequency oscillator and mixer at frequencies below ~300 mc or as grounded grid radio frequency amplifier.
High transconductance semi-remote cut-off amplifier tube designed for television RF and IF amplifier service. Precautions should be taken not to exceed dissipation rating with expected line-voltage fluctuations, especially with fixed-bias operation.
High-mu power output triode designed for service in dynamic coupled circuits using a type 76, 6P5GT/G or 6J5GT/G as a driver. Two 6AC5Gs may be used as a zero bias class B amplifier.
High-mu power output triode designed for service in dynamic coupled circuits using a type 76, 6P5GT/G or 6J5GT/G as a driver. Two 6AC5GTs may be used as a zero bias class B amplifier.
Compactron containing three high-mu triodes. It is designed for use primarily as a color-difference amplifier in color television receivers.
Triode-power amplifier pentode
Medium-mu triode in the 7-pin miniature construction. It is designed for local oscillator service in television receivers which operate in the UHF region, internal lead inductance is reduced by employing double connections to the plate and grid.
Miniature type RF pentode having a sharp cut-off characteristic and a high value of transconductance. In compact, light-weight equipment it is useful as an RF amplifier up to about 400 megacycles.
Metal, power-amplifier pentode primarily designed for use in the output stage of video amplifiers. The tube is capable of operating at high plate current levels and exhibits high transconductance and high power sensitivity.
High perveance triode for use as a vertical deflection amplifier in television receivers.
Miniature sharp-cutoff pentode. Its high transconductance and low input and output capacitance adapt it to use as a wide-band amplifier or as a reactance tube.
Miniature sharp cutoff pentode designed for use where only low plate and screen voltages are available. The 6AJ5 is especially suitable for operation at high frequencies.
Triode-heptode for use in F.M., AM/FM, A.M, and television receivers.
Miniature types used as rf or if amplifiers especially in high-frequency wide-band applications at frequencies up to 400MHz.
Heater-cathode type of tube intended for use in compact, light-weight equipment. Because of its small size, the 6AK6 can be used singly or in push-pull to effect a more compact design of power-line receivers.
Triple diode triode for F.M. or FM/AM broadcast receivers and for video and audio signal detection in television receivers.
The 6AL5 combines two independent diode units in the 7 pin miniature construction. Its high perveance permits high efficiency in either FM or AM detector service.
The 6AL7GT is an electron-ray indicator designed especially for use in AM-FM receivers. Through its use, precise tuning of either FM or AM signals is easily accomplished without the use of additional tubes or circuit components.
Medium mu triode and a sharp cutoff pentode. The pentode section may be used as an IF amplifier or a reactance tube; the triode section is well suited for use in low-frequency-oscillator, sync clipper, sync separator, and phase splitter circuits.
Miniature beam-power pentode designed for use in the audio-frequency power output stage of television and radio receivers. It may also be used as a triode-connected vertical deflection amplifier in television receivers.
Miniature double diode high mu triode designed for service as a combined first audio amplifier, detector, and AVC tube in radio receivers. However, the 6AQ6 employs a 150 mA heter.
Electro-Harmonix 6AQ8 dual triode preamp tube. Made in Russia.
High-mu twin triode
