Vacuum Tubes
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.
Beam pentode designed for use as a class "C" RF amplifier, oscillator, or frequency multiplier up to 175 Mc. It can also be used as a modulator or AF amplifier. Type 7558 is designed for fixed station equipment.
$14.90
Metal, sharp-cutoff pentode for use as a high-gain, audio-frequency amplifier or as a biased detector. The tube is a low-microphonic version of the 6J7 to which it is otherwise identical.
$12.90

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.
$24.90
Electro-Harmonix 6CA4 full-wave rectifier tube. Made in Russia.
$27.95
Beam power amplifier designed primarily for use in the output stage of a-c/d-c receivers. The 50A5 features high power sensitivity and high efficiency when operated at relatively low plate and screen voltages.
$4.90
Blue glass envelope. A sonically faithful reproduction of the original tubes with a robust construction encased in a thick glass envelope. The JJ KT88 delivers a powerful 42 Watts with plenty of headroom to spare. This tube has a tone that is warm and lively with a detailed and balance response.
Starting at $71.85
Miniature beam power amplifier especially designed for use in the power output stage of a-c/d-c receivers. Its small size and high efficiency make the tube especially useful where space limitation prevent the use of larger types.
$3.55
Filamentary full-wave high-vacuum rectifier designed for use in the power supply of a-c operated equipment
$29.90
Low voltage, low current drain battery type beam power output tube. It is designed for services with 90 volts of "B" battery and a single dry cell "A" battery.
$4.90
Compactron containing three high-mu triodes. It is designed for use primarily as a color-difference amplifier in color television receivers.
$7.90
Genalex Gold Lion PX300B power triode tube with gold pins. Made in Russia. In Europe during the 1930s the GEC (Genalex)/Marconi-Osram PX4 and PX25 power triodes were considered the finest audio triodes of their day. In keeping with the tradition of Genalex to provide the highest quality tubes, New Sensor has released the Genalex Gold Lion PX300B audio power triode. This tube is the highest quality 300B type available and is considered to be an upgrade in any 300B amplifier.
Starting at $195.45
Filament-type high-vacuum full-wave rectifier designed for service in power supplies of moderate current requirements. The electrical characteristics of the 5AZ4 are equivalent to those of the 5Y3GT.
$6.90
Compactron beam power pentode designed for use as the horizontal deflection amplifier in television receivers.
$8.90
Triple grid variable MU amplifier. It is suitable for use with AVC in RF and IF amplifiers as it minimizes cross modulation
$6.90
General purpose triode designed for service as an oscillator, detector, or amplifier. Except for heater voltage and current its characteristics are identical with those of the 56.
$20.90
9-pin miniature type high-mu twin triode, with heater having controlled warm-up time.
$8.90
Heater-cathode type high-mu triode designed for service as a high gain audio-frequency amplifier and is especially useful in resistance-coupled amplifier circuits in a-c or battery operated equipment
$6.95
Out of Stock
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
$3.90
Cathode type high vacuum rectifier designed for full-wave applications. The cathode is connected internally to the heater.
$29.90
Mullard 12AT7 / ECC81 dual triode preamp tube. Made in Russia.
$26.80
Filament type power-amplifier pentode tube designed for use in the output stage of battery operated equipment.
$4.90
Miniature, heater-cathode, twin diode for full-wave rectifier operation. High output current and small size make it especially suitable for compact amplifier designs.
$24.90
Colors Available:
$1.55
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.
