Vacuum Tubes

The JJ Electronic 7591 is a reliable and accurate reproduction of the classic tube. This 19 Watt pentode has been used in a variety of amplifiers including Hi-Fi amps and Ampegs. The JJ 7591 is a great replacement for any 7591 tube position.

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.

Miniature pentagrid-converter designed for use as a combined mixer and oscillator in superheterodyne circuits. Because of its small size and high operating efficiency, the 1R5 is especially adapted for compact, battery-operated equipment.

Miniature diode sharp-cutoff pentode designed for use as a combined detector, audio-frequency amplifier, and automatic-volume-control tube in compact, battery-operated receivers.

Electro-Harmonix 6CA7 Vacuum Tube Big bottle beam-tetrode version of EL34. Perfect EL34 replacement for Musicman amplifiers.

Electro-Harmonix 12BH7. Made in Russia.
Medium-Mu twin triode driver tube. 3.5 watts dissipation per plate.

Filamentary twin-diode designed for full-wave rectifier operation in power supplies that have d-c output current requirements up to approximately 125 milliamperes.

Electro-Harmonix KT88 Vacuum Tube High power kinkless-tetrode for use in amplifiers such as the Marshall Major. This tube is a favorite of audiophiles. Can be used in place of 6550 for a more "round" bass signature.

Mullard 12AU7 / ECC82 dual triode preamp tube. Made in Russia.

The Perfect Choice for Stereo Audio Applications - Ideal as a Balanced Driver. Latest revision providing great musical performance and rich tone. This TAD 12AU7A / ECC82 has especially strong systems which are selected to provide two symmetric triodes. The perfect choice for stereo audio applications and ideal as a balanced driver.

Mullard Reissue GZ34 (5AR4). Current production, made in Russia.
This is a copy of the most popular rectifier valve ever built by Mullard. It has a low internal voltage drop and a controlled heater warm up time which helps extend the life of the other valves in the amplifier by allowing them to heat up before plate voltage is applied.

Genalex Gold Lion ECC83/B759 (12AX7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC83/B759 tubes are considered among the best 12AX7 types ever made. They are hard to find and when they are available, they are expensive. They exhibit a large detailed soundstage that is sought after by discerning audiophiles who demand the highest quality sound. The reissue Genalex Gold Lion ECC83/B759 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

The JJ Electronic E88CC / 6922 is a great replacement for any 6922, 6DJ8, or E88CC tube. JJ implements a solid construction that those familiar with their preamp tubes will find familiar. This tube’s high end clarity and warm smooth mids make the JJ E88CC and excellent choice for Hi-Fi preamps and amplifiers.

A true to form reproduction of a classic tube that will work in most EL34 amps. The 6CA7 is often considered the American cousin to the British EL34. Sonically, this tube is closer to a 6L6 than an EL34 but without the sometimes harsh high end of the 6L6.

Metal duplex-diode high-mu triode. It is intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers.

0A2 or 150C2 - Voltage Regulator, Diode, miniature glow-discharge type.

A reproduction of the original tubes that captures the sound that made the KT77 famous. In their typical fashion, JJ has built this tube in a solid construction that is robust and highly reliable. This tube has more headroom than a typical EL34. This is an excellent tube for adding more power to the sound of an EL34 amp.

Russian made reissue of the original Tungsol.
The 5881 is the electrical equivalent to types 6L6 and 6L6G except that the plate and screen dissipation ratings have been increased approximately 20 percent. It embodies a complete mechanical redesign which results in greater resistance to shock and vibration.

5AR4 Ruby, Rectifier Tube

General-purpose triode designed for use as a detector, amplifier, or oscillator. Features include a relatively high transconductance and a medium amplification factor.

Triode-heptode for use in F.M., AM/FM, A.M, and television receivers.

Metal pentagrid converter. It is intended to perform the combined functions of the mixer and oscillator in superheterodyne receivers, especially those of the all-wave type. The 6SA7 is constructed to provide excellent frequency stability.

Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.

Miniature tube which contains a sharp-cutoff pentode and a medium-mu triode. Each section has a separate cathode and is electrically independent.
