Vacuum Tubes

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

Sovtek 6H30PI dual triode preamp tube with gold pins. Made in Russia. The 6H30 is a medium-mu dual triode with a very high-perveance cathode. The low plate resistance, combined with a superior linearity, and a true 4 watt per plate dissipation, make for a high performance voltage amp or driver.

Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in color television receivers. It is characterized by having a very low knee with a very high peak current of over an ampere.

The Psvane 6550A is a beam pentode with an octal base rated for up to 42W of plate dissipation. The Psvane 6550A is designed specifically for audio spectrum power-amplification and can deliver plenty of power in a push pull configuration with smooth and balanced response. 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 high-mu twin triode each section of which as an individual cathode connection suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, andindustrial-control circuits where high voltage gain is desired.

DC-AC heating twin triode

Pentode intended for use as A.F. amplifier.

Special quality tube designed for use as a wide band amplifier, cathode follower, series regulator tube for stabilized DC supply and output tube.

Special quality pentode designed for use as an amplifier

The 5U4G is designed for service as a power rectifier in AC operated receivers which require high currents

Full-wave high-vacuum rectifier for use in power supplies of moderate current requirements. The tube incorporates a unipotential cathode which is internally connected to the filament.

Transmitting triode

Pentagrid converter designed for service as a combined oscillator and mixer in AC, storage battery, and AC-DC operated receivers

Beam power tube with separate grid-no.3 base-pin terminal for "snivets" control. It is designed for horizontal-deflection-amplifier service in Low-B+ black-and-white TV receivers.

Miniature medium-mu twin triode designed primarily for use in low-level stages of high-gain audio-frequency amplifiers. The tube is specially designed to exhibit low noise and low microphonic output.

Miniature high-mu twin triode especially suited for use in resistance-coupled voltage amplifier, phase inverters, multivibrators, and other applications in which high voltage gain is desired.

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. The JJ KT88 is an excellent choice for Hi-Fi stereo equipment as well as guitar amplifiers. It can be used in place of 6550 tubes.

Transmitting triode for operation at maximum ratings up to 250 Mc.

A sonically faithful reproduction of the original tubes with a robust construction encased in a thick glass envelope. The JJ KT66 delivers a powerful 25 Watts with plenty of headroom. This tube has a tone that is warm, thick, and straightforward. With a more balanced sound than the 6L6GC, the JJ KT66 is an excellent choice for a full bodied tone.

The JJ Electronic EL509S is an eight pin octal based version of the EL509 / EL519. This modified version does not have the top plate cap which is instead wired to a pin on the octal base. This tube is rated for 700V and 42 Watts plate dissipation. The JJ EL509 is popularly used in output transformerless OTL amplifiers.

The JJ Electronic 6550 is a robust tube built in the rugged fashion that JJ is famous for. At 35 Watts, these tubes have a warm round tone with a thick and defined low end. The JJ 6550 is an excellent choice for bass heads, tube organs, and Hi-Fi amplifiers.

Genalex Gold Lion 6V6GT / CV511 beam-power tube. Made in Russia.

Electro-Harmonix 7868 power pentode tube with a magnoval style base. Made in Russia.

Sovtek 6C45PI single triode preamp tube. Made in Russia.
The 6C45P (6S45P in the western alphabet) is a high mu triode with a very high transconductance, incredible linearity, very low noise, and low plate resistance. This amazing tube will excel in small signal applications, as well as a driver, or anywhere really precise performance is required.
