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.
Vacuum Tube - 6AB4 / EC92, Triode
Miniature triode designed for use as a grounded-grid radio-frequency amplifier, frequency converter, or oscillator at frequencies below approximately 300 megacycles.
Vacuum Tube - 6J7 / EF36, Pentode, Sharp Cut-Off
Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.
Vacuum Tube - 6K7, Pentode, Remote Cut-Off
Variable mu pentode amplifier in the octal metal (glass) construction. It is suitable for use with AVC in RF and IF amplifiers and minimizes cross modulation.
Vacuum Tube - KT88, JJ Electronics, Blue Glass
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 $44.95

0A2 or 150C2 - Voltage Regulator, Diode, miniature glow-discharge type.
Vacuum Tube - 50B5, Beam Power Amplifier
Miniature beam-power amplifier designed primarily for use in the output stage of compact a-c/d-c receivers. The 50B5 features high power sensitivity and is capable of providing a relatively high power output
Vacuum Tube - 6SG7, Pentode, Semi Remote
Remote-cutoff pentode designed for use as a high-gain radio or intermediate-frequency amplifier. Features of the tube include high transconductance, low grid-plate capacitance, and a dual cathode connection
Vacuum Tube - 7591A, Tung-Sol Reissue
Tung Sol 7591A beam-power tube. Made in Russia.
Starting at $31.95
Vacuum Tube - 6BM8, Electro-Harmonix
Electro-Harmonix 6BM8 triode pentode tube. Made in Russia.
Contains one preamp triode and one power pentode in a 9 pin miniature package.
Vacuum Tube - 6CS7, Triode, Dissimilar Double
Miniature double triode having dissimilar sections. Section no. 1 is intended for operations as a vertical deflection oscillator and section no. 2 as a vertical deflection amplifier.
Vacuum Tube - 6SC7, Triode, Dual, HI-MU
High-mu twin triode designed primarily for use as an AF voltage amplifier. Featuring a special shielding arrangement to reduce hum, the tube is well suited for low-level audio amplifier service.
Vacuum Tube - 12AT7 / B739, Genalex Gold Lion, Gold Pin
Genalex Gold Lion ECC81/B739 (12AT7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC81/B739 tubes are considered the best 12AT7 types ever made. They are also among the rarest types available. They exhibit a large detailed soundstage that is characterized by an expressive midrange, deep tight bass, and a smooth extended high end. The reissue Genalex Gold Lion ECC81/B739 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.
Vacuum Tube - 12SK7, Pentode, Remote Cut-Off
The T-12SK7 is the same as the 6SK7 except for heater ratings.
Vacuum Tube - 6CB6A / 6CF6, Pentode, Sharp Cut-Off
Miniature pentode designed for use as a radio-frequency or intermediate-frequency amplifier in television receivers. Features of the tube include high transconductance and low interelectrode capacitances.
Vacuum Tube - 6SF5GT, Triode, HI MU
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
Vacuum Tube - 12AT7 / ECC81, Triode, Dual, HI-MU
The 12AT7 is a miniature, high-mu, twin triode designed for use as a grounded-grid radio-frequency amplifier or as a combined oscillator and mixer at frequencies below approximately 300 megacycles.
Vacuum Tube - 12BV7 / 12BY7A, Pentode
Miniature power pentode designed primarily for use as the video output amplifier in television receivers. Like the 12BY7, it features high transconductance, high power sensitivity, and low interelectrode capacitances.
Vacuum Tube - 6BN4A, Triode, HF
Miniature medium-mu triode designed for as a radio-frequency amplifier in a VHF television tuner.
