Vacuum Tubes

The Svetlana 12AX7 is a premium 12AX7 tube from Russia. Known for their smooth drive and clarity, these tubes are praised by both guitar players and HiFi users alike. The Svetlana 12AX7 is compatible in any 12AX7 or ECC83 position. “Svetlana tubes are quite simply the absolute best. We design and manufacture our tubes, engineered for demanding high fidelity, reliability and overall warmth. Be sure to insist on genuine Svetlana vacuum tubes the next time you retube -- you'll be getting the absolute best possible tubes for any demanding application.” -Svetlana

Tung Sol 5AR4 rectifier tube. Made in Russia. Premium directly heated heavy duty rectifier Diode. Helps extend the life of the other valves in the amplifier by allowing them to heat up before plate voltage is applied. Tung-Sol tubes reflect the best in vintage construction with unsurpassed tone and reliability.

• Low internal voltage drop & controlled heater warm up time
• Excellent choice for both Hifi and instrument amplification
• Replacement/upgrade for all 5AR4/GZ34 types

Heater-cathode type high-mu triode designed for service as a high gain audio-frequency amplifier and is especially useful in resistance-coupled amplifier circuits in a-c or battery operated equipment

Beam power pentode primarily designed for use as the horizontal-deflection amplifier in television receivers.

Sharp-cutoff pentode of the 9-pin miniature type intended for use as an audio amplifier in applications requiring reduced microphonics, leakage noise, and hum.

Miniature heptode primarily designed to perform the combined functions of the mixer and oscillator in superheterodyne circuits in both the standard broadcast and FM bands.

Dissimilar double-triode designed for use as a combined vertical-deflection oscillator and amplifier in television receivers. Section 1 is intended for service as an oscillator and section 2 as an amplifier.

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.

The Psvane KT88 is a high quality, high power, beam tetrode with an octal base. The KT88C is notable for its warmth and clarity across the entire audio spectrum. 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. Psvane has since acquired their own manufacturing facilities with the goal of improving the production and performance of vacuum tubes.

9-pin miniature type high-mu twin triode, with heater having controlled warm-up time.

Miniature double triode having dissimilar sections. Section no. 1 is intended for operations as a vertical deflection oscillator and section no. 2 as a vertical deflection amplifier.

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.

Russian made reissue of the original Tungsol.
The 5881 is the electrical equivalent to types 6L6 and 6L6G except that the plate and screen dissipation ratings have been increased approximately 20 percent. It embodies a complete mechanical redesign which results in greater resistance to shock and vibration.

Triple grid general purpose detector amplifier.

Miniature remote-cutoff pentode designed for use as a radio-frequency or intermediate frequency amplifier in compact, battery-operated equipment.

Premium high-voltage power pentode, featuring improved materials and workmanship over the original EL34B. Higher impedance design with increased touch responsiveness.

• Unique clipping characteristic with a hint of 6L6 sound
• Velvety-smooth in HiFi applications, full & rich-sounding in guitar amps
• 6CA7 equivalent

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.

High quality 8W power resistors from Ohmite’s Brown Devil® series. These resistors are used in original Fender® tweed amps. Ohmite’s Brown Devil® is a small, exceptionally durable power resistor. It features all-welded con-struction and rugged, flame resistant conformal lead free vitreous enamel coating to ensure successful performance under high temperatures.The wirewound 200 Series has a hollow-core con-struction, which accommodates rigid mounting with brackets or thru bolts.Mounting brackets not included with resistors. Features

• Rugged lead free vitreous enamel coating
• All-welded construction
• Self supporting terminal mounting option
• 8W power rating
• Flame-resistant lead free vitreous enamel coating

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.

Miniature tube which contains a sharp-cutoff pentode and a medium-mu triode. Each section has a separate cathode and is electrically independent.

Miniature tube containing three high-perveance diodes and a high-mu triode in the same envelope. One of the diodes has a separate cathode connection. The tube is designed for use as a combined AM and FM detector and audio-frequency amplifier.

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.

Electro-Harmonix 6973 Power Tube Beam power amplifier used in vintage Gretsch and Magnatone amplifiers. This is a real 6973, not a rebrand of a "close" tube.
