Vacuum Tubes

Premium high-voltage power pentode. An extremely faithful reissue of the XF2 Mullard EL34 from the 1960s.

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

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.

The Psvane ECC82 is a high quality, medium gain, dual triode. This tube has a noval base and is noted for its rich and dynamic sound. The Psvane ECC82 works well in any ECC82 / 12AU7 position. The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment. When designing the Classic Series, Psvane collected the most sought-after NOS tubes and analyzed each element of their construction, incorporating the most effective manufacturing techniques to produce stable tubes with excellent sound. Whether used in guitar amplifiers or hifi stereo systems, the Psvane Classic Series vacuum tubes excel in all applications. Psvane has been producing high quality vacuum tubes since 2011. The Psvane team originally formed in Shuguang’s high-end tube division but eventually split off to form their own brand.

The JJ Electronic ECC99 is a noval based dual triode. This tube features a rugged construction and is also available with gold pins. The ECC99 is typically used as a driver for power triodes in 2A3 and 300B amplifiers but can also be used as a power tube in small amps and headphone amps. This tube can also be a functional replacement for 5687, E182CC, 6840, and 6BL7 tubes. Note: Sockets on some of these types could have a different set-up.

Low-noise Tube for Best Clean Tone! The TAD Selected 5751 is Tube Amp Doctor's first choice for noticeably improved clarity, smoothness, and a true vintage tone character for most guitar amps!

High frequency twin triode preamplifier tube used in studio and hi-fi equipment.

Premium directly heated heavy duty rectifier Diode. Re-issue of the most popular rectifier valve ever built by Mullard. Helps extend the life of the other valves in the amplifier by allowing them to heat up before plate voltage is applied.

• Low internal voltage drop & controlled heater warm up time
• Excellent choice for both Hifi and instrument amplification
• Replacement/upgrade for all 5AR4/GZ34 types

The Tube Amp Doctor 5Y3GT / 6087 is a small bottle rectifier designed to perform closely to the original rectifier tubes used in many 1950s tweed amplifiers. This rectifier offers high reliability due to its rugged construction and the Tube Amp Doctor Premium Selection process. The TAD 5Y3GT is a great tube for vintage style sag compression.

Miniature medium-mu twin triode suitable for a wide variety of general-purpose amplifier, oscillator, and multivibrator applications.

Pentode amplifier having a remote control grid characteristic and utilizing the miniature construction. As a RF amplifier, it is characterized by high transconductance and low grid-plate capacitance.

Dissimilar double triode in the 9-pin miniature construction. It is especially suitable for applications requiring a high gain voltage amplifier and a cathodyne type phase-inverter.

Miniature sharp-cutoff pentode for use as a wide-band, high-frequency amplifier. It is also useful in video and audio amplifiers, oscillators, mixers, frequency multipliers, and cathode followers.

Due to many requests by fans, the Tung-Sol EL84/6BQ5 has been reissued. The Tung-Sol EL84 / 6BQ5 was a popular OEM tube for American-made EL84 / 6BQ5 guitar amplifiers, such as those built by Gibson and Harmony. Due to its rugged construction and conservative ratings, it is the most reliable current production EL84 type available for use in Vox AC-30 type amplifiers. In addition, its linearity and tone characteristic make it the ideal replacement for EL84 hi-fi amplifiers, such as those built by Fisher, Scott, and Harmon-Kardon. Tube measurements are as follows:

• Height: 2.75” (without pins)*
• Diameter: 0.87”*

*Note: Due to the method of production in regards to the glass, measurements may vary slightly.

The 6100 / 6C4WA is a heater-cathode type medium-mu triode of miniature construction, suitable for use as a class C amplifier and oscillator. This type is characterized by long life and stable performance.

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.

Miniature heptode primarily designed to perform the combined functions of the mixer and oscillator in superheterodyne circuits in both the standard broadcast and FM bands.

Miniature, medium-mu twin triode designed primarily for use as a vertical-deflection amplifier in television receivers. The two sections may be employed in parallel, or as a combined vertical-deflection amplifier and vertical oscillator.

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 half-wave rectifier for use in line-operated equipment having series-connected heaters. The heater is tapped to permit operation of a panel lamp.

Miniature medium-mu twin triode suitable for use in a wide variety of general-purpose applications. It is particularly useful as a vertical-deflection oscillator and horizontal-deflection oscillator in television receivers.

Remote-cutoff pentode. It is designed for use as a high-gain radio-frequency or intermediate-frequency amplifier in a radio receiver.

Electro-Harmonix 12AY7/6072 Twin triode preamplifier tube used in Fender Tweed amplifiers.

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.
