Vacuum Tubes

The JJ Electronic EF806S is a high quality reproduction of the classic EF86. This pentode features a robust construction with the internal shielding used in the original tubes. The JJ EF806 can be used in any EF86 circuit including microphones and amplifiers.

Super Premium power pentode, highest quality in current production. Perfect for Vox AC30, from soft overdrive and organic sustain to great harmonic crunch. Used in many vintage HiFi applications.

• Unique single halo type getter & plate coating
• N709/6BQ5 equivalent

Premium high-voltage power pentode, featuring improved materials and workmanship over the original EL34B. Higher impedance design with increased touch responsiveness.

• Unique clipping characteristic with a hint of 6L6 sound
• Velvety-smooth in HiFi applications, full & rich-sounding in guitar amps
• 6CA7 equivalent

The Sovtek 5881WXT is the same as the 5881 but with a full size base for easy installation in vintage amp designs. The Sovtek 5881 delivers a warm, round tone that "sweetens" any vintage or modern guitar amp design. Built to rigid military standards, the 5881 will tolerate higher voltages than any other 6L6. In fact, they're frequently used as replacements for the old 7027 model in vintage Ampegs. Extremely consistent from piece to piece. The Sovtek 5881 has a heater voltage of 6.3 volts at 0.88 amperes.

Electro-Harmonix 12DW7 dual triode preamp tube. Made in Russia.
12DW7 combines one triode of 12AX7 and one triode of 12AU7 in a dual triode package. System 1 (pins 6, 7, 8) is the high-mu 12AX7 triode and system 2 (pins 1, 2, 3) is the medium-mu 12AU7 triode.

Rugged high mu twin triode designed for service as a resistance coupled amplifier or phase inverter in applications requiring resistance to shock and vibrations.

Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. Very low knee voltage, high plate-to-screen ratio, and high peak current capability.

Superior power beam tetrode, engineered for demanding high fidelity, reliability and overall warmth. Traditional brown base.

Tung Sol 6L6GC “STR” beam-power tetrode tube. Made in Russia. The Tung-Sol legacy continues with the introduction of the new 6L6GC STR. The ultimate in musical tone and smooth overdrive, the STR delivers the sound that established Tung-Sol as the benchmark of quality. Built to the same “Special Tube Request” specs of leading amplifier manufacturers of the 1960s, the 6L6GC STR is a rugged and reliable power tube for use in the most demanding guitar amplifier circuits.

Tung Sol 5751 dual triode preamp tube. Made in Russia. NOS specs call the 5751 a “special 12AX7” having a high-mu amplification factor of 70.

Sharp cutoff pentode of the 7 pin miniature type with heater having controlled warm-up time.

Power amplifier pentode designed for use in the audio-frequency power output stage of television and radio receivers and in high fidelity amplifiers.

Beam-power pentode primarily designed for use in the power output stage of high-fidelity audio-frequency amplifier systems.

General purpose triode designed for service as an oscillator, detector, or amplifier. It is similar in characteristics to the 6C6, 6J7, and 57 with triode connection.

High-vacuum, heater-cathode type of tube designed to indicate visually the effect of change in the controlling voltage. Essentially a voltage indicator and as such is particularly useful to facilitate exact tuning of a radio receiver.

Duodecar type used as horizontal-deflection amplifier in television receivers.

Cathode type twin triode designed for use as a voltage amplifier

Consists of two dynamically coupled triodes and is designed for service in the power output stage of AC and storage battery operated receivers. All necessary biases are supplied internally

Sovtek 6SC7 high-mu twin-triode preamp tube. Made in Russia.

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.

Superior power Beam tetrode with large plate dimensions and improved grid structure for increased power handling capabilities. Excellent tone and performance compared to most other 6L6 or KT66 types.

Electro-Harmonix 6CG7 dual triode preamp tube. Made in Russia.

Electro-Harmonix 6BM8 triode pentode tube. Made in Russia.
Contains one preamp triode and one power pentode in a 9 pin miniature package.

Superior "Black base" high-voltage power pentode. Most common power pentode found in British amplifiers such as Marshall, Hiwatt, Laney, and Sound City. The EL34EH defines the classic British rock sound of the 1960s and 1970s. Perfect EL34 for vintage equipment and for improved performance of modern amps. Extremely musical and predictable, with a sound that is rich, smooth, and detailed without being edgy.
