Vacuum Tubes

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.

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.

Compactron beam-power pentode primarily designed for use as the horizontal-deflection amplifier in television receivers. A separate connection is provided for the beam plates to minimizes "snivets".

Beam pentode designed for use in the audio-frequency power output stage of radio and television receivers. Features include high power sensitivity and high efficiency at relatively low plate and screen voltages.

Cathode type rectifier designed particularly for use in automobile receivers.

Combines a high mu triode and two independent diode units in the 7-pin miniature construction. It permits a single tube to function as detector, AVC rectifier, and audio amplifier.

The Tube Amp Doctor KT-66 is an incredible remake of the classic British tube. With its large glass envelope contoured by smooth curves tapering into a rounded brown base, the TAD KT-66 not only looks like the original, it performs like the original. This KT66 offers plenty of headroom for a thick full bodied sound with smooth yet articulate highs. The KT-66 is famously used in vintage British plexi amps and makes a great replacement for that style of amplifier and many others. The TAD KT66 is matched for both plate current and transconductance and passes all of the tests of the TAD Premium Selection process. The TAD KT-66 can be used in any KT-66 position as well as 6L6GC and 5881 amps that can supply the required 1.27A for the heater.

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

The Psvane 6SN7GT is a high quality, medium gain, dual triode with an octal base. The Psvane 6SN7GT is an excellent preamp tube with a classic look and sound. The Psvane 6SN7GT works great in any 6SN7 position. 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.

The 12AU6 is a pentode amplifier having a sharp cut-off control characteristic using the miniature construction. With high transconductance, low grid-plate capacitance, it is intended for service as either an RF or AF amplifier.

Miniature beam pentode primarily designed for use in the audio-frequency power-output stage of radio receivers. The tube features high power sensitivity and high efficiency at relatively low plate and screen voltages

Miniature, remote-cutoff pentode designed primarily for use as a high-gain radio-frequency or intermediate-frequency amplifier. Features include low grid-plate capacitance, relatively high transconductance, and low heater current.

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

Transmitting triode for oscillator applications requiring unusually stable characteristics.

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.

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.

Miniature triode designed for use as a grounded-grid radio-frequency amplifier, frequency converter, or oscillator at frequencies below approximately 300 megacycles.

Miniature tube which contains a sharp-cutoff pentode and a triode in one envelope. Each section has a separate cathode and is electrically independent. Primarily intended as a combined triode oscillator and pentode mixer in television receivers.

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.

Miniature, medium-mu twin triode for use as a radio-frequency amplifier or as a combined oscillator and mixer in VHF television receivers. It my also be used as an audio-frequency amplifier.

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.

Pentode for use as RF, IF, or video amplifying valve or mixing valve in television receivers.

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 6SC7 high-mu twin-triode preamp tube. Made in Russia.
