Vacuum Tubes

Premium Octal beam Tetrode, an exact copy of the KT88 valve manufactured by Marconi-Osram for Marshall in the late 1960s and 70s. Powerful, balanced and detailed soundstage with full bass.

• Direct replacement for any 6550 types
• Excellent replacement output valve for the Marshall Major, retains the original sound
• Equally well suited for hifi

The Psvane 12BH7 is a high quality, medium gain, dual triode with a noval base. With 3.5W plate dissipation per triode, the Psvane 12BH7 is an excellent driver tube and works well in any 12BH7 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.

Pentagrid converter designed to minimize frequency drift. They are intended for service as combined oscillators and mixers in AC, storage battery, and AC/DC operated superheterodynes.

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.

Small, sturdy, beam power tube having a high efficiency and high power sensitivity. It is designed for use as an rf power amplifier and oscillator as well as an af power amplifier and modulator in both mobile and fixed equipment.

Triple diode triode for F.M. or FM/AM broadcast receivers and for video and audio signal detection in television receivers.

Miniature semi-remote-cutoff pentode designed primarily for use as an intermediate frequency amplifier in television receivers.

Miniature beam power pentode designed for service as an audio output amplifier. It features high power sensitivity at relatively low plate and screen voltages.

The 6CW4 isa high-mu triode for use as a grounded-cathode, neutralized RF-amplifier tube in tuners of VHF television and FM receivers.

Semi-remote cutoff pentode. It is designed for service in the IF stages of color and monochrome television receivers and may be used in the tuners of such sets as an AF amplifier.

Semi-remote cutoff double triode designed for use as a cascode VHF amplifier. It features extremely high gm, low capacitance, and low noise.

Dissimilar section double triode intended to serve the combined functions of the vertical deflection oscillator and amplifier. It features the T-9 bulb with integral wafer base which fits the standard 9 pin miniature socket.

Indicator tube with amplifying triode for use as tuning indicator or for modulation control

General-purpose power pentode that may be used either in audio output amplifier or video power output amplifier stages of television receivers.

Sovtek 6H30PI dual triode preamp tube. Made in Russia.
The 6H30 is a medium-mu dual triode with a very high-perveance cathode. The low plate resistance, combined with a superior linearity, and a true 4 watt per plate dissipation, make for a high performance voltage amp or driver.

"Svetlana tubes are quite simply the absolute best. We design and manufacture our tubes, engineered for demanding high fidelity, reliability and overall warmth."

Triple grid sharp cut-off amplifier. It is designed for service in high gain RF and IF amplifier applications and for limited service in FM receivers. The double cathode connection is useful in reducing cathode circuit coupling.

Sharp-cutoff pentode designed for use as a biased detector or high-gain amplifier.

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

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.

Triode, Dual, HF

Pentode type amplifier tube with remote cutoff characteristics designed for use as a high frequency amplifier in radio receivers.

Diode-audio pentode designed especially for service as a combined diode detector and pentode audio amplifier. The diode plate is located at the negative end of the filament.

Screen grid R-F amplifier.
