Vacuum Tubes

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.

The Psvane ECC81 is a high quality, medium gain, dual triode. This tube has a noval base and is praised for its lush and detailed sound. The Psvane 12AT7 works well in any ECC81 / 12AT7 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.

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.

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

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.

The TAD 6L6GCM-STR REDBASE is Tube Amp Doctor's latest 6L6GC; designed and built to be the best 6L6 type tube ever manufactured. A high claim, but Tube Amp Doctor is sure that they have achieved exactly that. In terms of sound, the TAD 6L6GCM-STR REDBASE produces the powerful but always defined bass response known from the legendary american built NOS RCA 6L6GC, with clear, unobtrusive and yet transparent highs.

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.

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.

Genalex Gold Lion ECC83/B759 (12AX7) dual triode preamp tube with gold pins. 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.

Miniature duplex-diode, high-mu triode intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers. The triode section incorporates a high amplification factor

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.

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

The all new TAD-EL84-STR Redbase brings together the best of both - the famous EL84-Cz and the EL84M. We opted for the thickest glass possible and the heaviest construction available, just like the Russian EL84M, and combined these features with the sonically most promising cathode plate options, in order to meet and exceed the tonal quality of the EL84-Cz especially with regard to its linearity over the entire frequency range. Finally we added the gold grid wire in order to improve overall reliability. The sound can be described as very harmonic in the middle and treble frequencies, without adding too much power to the bass. The result is the best EL84 in current production. Note: Due to its diameter of 22.5mm, the TAD EL84-STR does not fit into older Marshall DSL401 made till week #20 in 2014 and the UK made VOX AC15 TBX amplifiers from the same time period.

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.

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

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.

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.

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.

The Sovtek 6550WE was designed to be the finest 6550 ever produced. Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550s. The resulting performance advantages include 5% higher output power, increased reliability, greater headroom, and superior tone. The 6550WE features a metal-ringed base for increased power-handling capabilities.

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

Miniature, medium-mu twin triode for use as a frequency divider in computer applications.
