Vacuum Tubes

Russian Tung-Sol 6EU7 tube. High-Mu twin triode with 9 pin miniature base. Made in Russia.

Tweed Up Your Amp! Vintage tone for original vintage Fender tweed amps. The original tube for all those Fender® tweed amps from the 50s. Brings back the original sound to your tweed amp.

The 5881 is a very reliable tube that is widely used in many current production tube amplifiers. It has a warm tone with good 'bite.' This modern version is able to tolerate higher voltages than its 5881 / 6L6 cousins. 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.

Miniature twin-triode primarily designed for service in computer applications. Each triode section features a high zero-bias plate current, a sharp-cutoff characteristic, and a separate cathode connection.

General purpose triode designed for service as an oscillator, detector, or amplifier. It is similar in characteristics to the 6C6, 6J7, and 57 with triode connection.

The impossible search for tubes to use in your high end studio equipment is over. JJ Electronic has spared no effort in creating a tube that meets the quality demands of working studios with the JJ 6386-LGP. This solidly constructed tube features gold pins.

Beam-power pentode designed for use in the audio frequency power output stage of television and radio receivers. Capable of supply high power output with high sensitivity, high efficiency, and low third and higher-order harmonic distortion.

Blue glass envelope. The JJ Electronic E34L adds more power to a standard EL34 due to its higher grid voltage rating. This increase gives the tube more headroom and a tighter response on the low end. The wide frequency response of this tube offers excellent harmonics that work in a variety of genres ranging from the cleanest cleans to rich and aggressive breakup.

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.

Miniature, filamentary, sharp-cutoff pentode intended for radio frequency or intermediate frequency amplifier use in battery-operated receivers.

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.

Superior high-power Octal Beam Tetrode, suitable for any amp using 6550 or KT88. Designed to hold up in even the most punishing environment of high powered bass amps, such as Ampeg SVT. With 42 watts of plate dissipation in tetrode operation and 44 watts in triode, power is improved even over desirable vintage types.

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 6100 / 6C4WA is a heater-cathode type medium-mu triode of miniature construction, suitable for use as a class C amplifier and oscillator. This type is characterized by long life and stable performance.

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.

Medium-mu twin triode suitable for use in a wide variety of general-purpose amplifier and phase-inverter applications. It is also especially useful as a blocking oscillator, multivibrator, or vertical deflection amplifier in television receivers.

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

Filamentary twin-diode designed for full-wave rectifier operation in power supplies that have d-c output current requirements up to approximately 125 milliamperes.

The 50L6GT is designed for service in the output stage of ac/dc receivers. It delivers a high power output with high power sensitivity from low supply voltages.

High grade tube. Tweed Up Your Amp! Vintage tone for original vintage Fender tweed amps. The original tube for all those Fender® tweed amps from the 50s. Brings back the original sound to your tweed amp.

Medium-mu twin triode intended for service in radio and television receivers or in audio amplifiers. The tube is suitable for use in a variety of stages, such as general-purpose amplifier, phase inverter, oscillator, or multivibrator.

Miniature medium-mu twin triode suitable for a wide variety of general-purpose amplifier, oscillator, and multivibrator applications.

The 6K6GT is an indirectly heated cathode type power amplifier pentode designed for service in the output stages of AC, AC/DC and storage battery operated receivers.

Sovtek 12AX7WB dual triode.
