Vacuum Tubes

Octal power tube (Max Plate Watts = 14W) Beam power tetrode with a specially developed cathode coating, careful alignment of the grid, tri-alloy plate material for flawless performance up to 475 volts. Perfect for high plate voltage amplifiers like the Fender Deluxe Reverb.

Electro-Harmonix 6SN7 medium-mu twin triode preamp tube. Made in Russia. New low noise HiFi 6SN7.

Electro-Harmonix EF86 pentode preamp tube. Made in Russia.

High current, twin power triode widely used in electronically regulated power supplies. The high perveance of this tube permits it to pass large currents at low plate voltages, thus providing for efficient series regulation. Shouldered glass (ST-16) envelope.

Pentode amplifier designed for application in power output stages of receivers

High-mu power output triode designed for service in dynamic coupled circuits using a type 76, 6P5GT/G or 6J5GT/G as a driver. Two 6AC5Gs may be used as a zero bias class B amplifier.

Sovtek 12AX7WB dual triode.

Russian made Mullard reissue EL84. Copy of the original. Black plates, carbonized screens, and gold plated grids. This tube was the "Voice of the Vox AC-30." A mainstay of affordable quality hi-fi amplifiers of the 1960s. 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.

Half-wave high-vacuum rectifier which may be used with either choke or condenser input to the filter.

Sovtek 6SN7GT dual triode, medium MU. Made in Russia.

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!

Superior medium-mu twin triode driver tube for hifi use. 3.5 watts dissipation per plate. New design of excellent quality

Octal rectifier tube (Max DC output current = 125 mA) An indirectly heated diode intended for rectification of commercial-frequency alternating current. It has a 140 mA maximum output and filament voltage of 5 V and a filament current of 2 A ± 0.2 mA.

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 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.

Octal rectifier tube (Max DC output current = 250 mA)

The Psvane 5U4G is a directly-heated rectifier with an octal base. The Psvane 5U4G features the iconic shouldered bottle of the original 5U4G rectifiers. This tube is a great rectifier for any type of amplifier. 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.

Electro-Harmonix 12AT7WC dual triode preamp tube. Made in Russia. “Xtra Low Microphonic”. Small plate format dual triode, with low microphonics and superior dissipation compared to NOS originals. Ideal for reverb circuits.

Power rectifier with low internal voltage drops. It is designed for service in AC operated receivers that require high currents

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