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 remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.

The Psvane 5881 is a high quality beam power pentode with an octal base. The Psvane 5881 is noted for its outstanding sound and is an excellent choice for both guitar and stereo amplifiers. The 5881 is similar to 6L6 tubes but with a maximum plate dissipation of 23W. The Psvane Classic Series is focused on the reproduction of popular vacuum tubes found in classic audio equipment.

9 pin miniature type beam power tube. Its heater has a controlled warm-up time.

General-purpose triode designed for use as a detector, amplifier, or oscillator. Features include a relatively high transconductance and a medium amplification factor.

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.

Heather-cathode type high-mu twin triode of miniature construction designed for use as a resistance-coupled voltage amplifier or phase inverter and blocking oscillator.

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.

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.

The Tube Amp Doctor EF86 / 6267 is a low noise and low microphonic version of the vintage pentode. These tubes were famously used in classic HiFi equipment and microphone preamps. The original Vox® AC15 circuit also used an EF86 and now, thanks to its recent availability, there are plenty of options for guitar amplifiers utilizing this unique tube. The TAD EF86 / 6267 meets all of the standards of the Tube Amp Doctor Premium Selection process. This tube has a rugged construction featuring an aesthetically pleasing perforated shield. The TAD EF86 / 6267 will work in and EF86 or 6267 position.

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.

Sharp cut-off general purpose amplifier. With the exception of heater and capacitance ratings, the electrical characteristics are similar to those of the 6C6.

Metal duplex-diode high-mu triode. It is intended primarily for use as a combined detector, amplifier, and automatic-volume-control tube in radio receivers.

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.

Higher in gain than the 5881WXT, with full base. Modelled after the vintage RCA 6L6GC "blackplate," the Sovtek 6L6WXT+ features larger plate dimensions and improved grid structure for increased power handling capabilities.
The 6L6WXT+ also features mica spacers with metal springs to eliminate tube rattle and microphonics. The Sovtek 6L6WXT+ yields a 20% higher output than the Sovtek 5881WXT and offers superior tone and overall performance to any 6L6 or KT66. The ultimate 6L6, the WXT+ will improve the sound of any 6L6 guitar amplifier.
