Vacuum Tubes

The Psvane EL84 is a high quality output pentode. It has a noval base and maximum plate power of 12W. The Psvane EL84 captures the classic sound of this tube and is an excellent choice for both guitar and stereo amplifiers. 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.

Converter tube designed for stable operation over an extended frequency range. It consists of a heptode mixer and a triode oscillator, having a common cathode. The injector grid of the heptode is internally connected to the triode grid.

The JJ Electronic 12AX7 / ECC83 has quickly become a modern classic in preamp tubes. Its rugged design and rich harmonics make this tube an obvious choice for musicians who need a reliable and high quality tube at a reasonable price. The balanced tone of the JJ 12AX7 works well in any amp.

Heater-cathode type twin triode designed for use as a class B power amplifier in the output stage of a-c or battery operated equipment. It may be used in other applications such as a biased detector, oscillator phase inverter or class A amplifier

A good choice for phase inverters, reverb drivers, and general preamp use. This tube offers low noise, low microphonics, and warm smooth tones at a great price. Like all JJ tubes, it has a rugged construction that doesn’t compromise the sound of your amp. The JJ 12AT7 is a solid replacement for any 12AT7, ECC81, or 6201 tube. It can also be used to replace 12AX7 tubes in position 1 to reduce gain.

A medium gain dual triode built with the quality and reliability that we’ve come to expect from a JJ tube. This 12AU7 offers smooth tones and clear definition which is why it’s no surprise that this tube is often found in hifi equipment as well as guitar amplifiers.

Screen grid R-F amplifier.

General purpose medium-mu double triode using the 9-pin button all-glass construction. The tube is characterized by high perveance and high emission capabilities.

Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.

Duodecar type tube used in audio-frequency circuits. The triode unit is used as a voltage amplifier; the pentode unit is used as a power amplifier.

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.

Medium-mu triode - modulator, oscillator, amplifier.

Xenon filled four electrode thyratron with negative control characteristic. This tube is designed for relay applications for grid-controlled rectifier service.

High-mu twin triode

Sharp cutoff pentode intended for critical industrial applications where 10,000 hour life, extreme uniformity, rigid construction, and exceptional stability are paramount.

Beam power tube - high power sensitivity RCA "Dark Heater" with 12 to 15 volt range.

High perveance triode for use as a vertical deflection amplifier in television receivers.

Glass octal type for industrial and military applications.

High-transconductance twin triode designed primarily for use as a combined vertical deflection amplifier and vertical oscillator in television receivers.

Sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.

Compactron beam-power pentode designed for use as the horizontal deflection amplifier in television receivers.

Electron-ray tuning indicator

Combines two diode units and a high-mu triode in a single envelope. Each section uses a common cathode. It is intended for service as a combined detector, AVC source, and high gain audio amplifier.

General purpose filament type triode designed for service in battery operated receivers. With the exception of capacitances, its ratings and characteristics are identical with those of the 1H4G.
