Vacuum Tubes

Miniature, medium-mu, semi-remote cutoff twin triode intended for application as a VHF cascode amplifier in a television receiver.

Miniature tube which contains two dissimilar triodes in one envelope. The tube is intended for use as a combined vertical deflection oscillator and amplifier in television 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.

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

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.

Miniature sharp-cutoff pentode designed primarily for use as a high gain radio-frequency or intermediate-frequency amplifier. Low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications.

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

The JJ Electronic 7027A offers the same reliability and tone as the JJ 6L6GC but with the correct pinout for vintage amplifiers that use 7027 tubes like older Ampegs. At 30W, this tube delivers plenty of headroom. The highs are clear and responsive with warm mids and tight solid lows. Known for their reliability and articulation, the JJ 7027A is a great option guitar amplifiers and Hi-Fi stereo equipment.

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

Medium-mu twin triode suitable for use in a wide variety of general purpose amplifier and phase-inverter applications. Except for heater characteristics and ratings, the 12SN7GA-B is identical to the 6SN7GTB

Rediscover the classic tone of the Shuguang 12AX7B vacuum tube. Crafted with meticulous attention to detail, these 9-pin dual triodes embody the essence of classic tube amplification while offering modern performance and reliability. The Shuguang 12AX7B is a favorite for high gain amplifiers but works just as well in clean settings. Renowned for its versatility and sonic clarity, the 12AX7B breathes life into your amplifier, delivering rich harmonics and a smooth, balanced sound that enhances every note you play. From clean, pristine tones to gritty overdrive, these tubes provide the dynamic range and responsiveness that discerning musicians demand. Built to last and engineered for consistent performance, the Shuguang 12AX7B tube ensures reliable operation even in the most demanding environments. Whether you're recording in the studio or commanding the stage, these triple mica tubes deliver exceptional tone and stability every time.

Miniature, medium-mu twin triode for use as a frequency divider in computer applications.

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.

Superior power Beam tetrode with large plate dimensions and improved grid structure for increased power handling capabilities. Excellent tone and performance compared to most other 6L6 or KT66 types.

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 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.

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.

Miniature full-wave high-vacuum rectifier intended for use in power supplies which have low d-c output-current requirements.

The Sovtek 6550WE was designed to be the finest 6550 ever produced. Thicker plates, improved heat dissipation, higher transconductance, and increased linearity are just some of the inherent aspects of the new Sovtek super 6550s. The resulting performance advantages include 5% higher output power, increased reliability, greater headroom, and superior tone. The 6550WE features a metal-ringed base for increased power-handling capabilities.

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.

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.

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.
