Vacuum Tubes

The TAD KT88-STR Redbase® is built in the style of the early British MOV KT88 with the big and heavy glass envelope and beautifully polished metal base. The Redbase® features a gold control grid for outstanding performance and reliable stability. A breath-takingly big and precise tone and great appearance make the new TAD KT88-STR Redbase® the best choice for both, high-end audio applications and powerful bass guitar amps, providing a natural and three dimensional tone with pleasingly full warmth and fine, subtle highs. A very musical response, with great sound and finest details in mids and top-end; a linear and harmonious overall response with a very organic tone, make the TAD KT88-STR Redbase® TAD’s favorite tube in the KT88 and 6550A class.

High quality W22 resistors from Welwyn / TT Electronics W20 Series. These 7W wirewound resistors are a great choice for screen grid and cathode bias resistors in tube amplifiers. The brown enamel coating used by Welyn looks great in vintage and vintage-style amps. These resistors can be found in many vintage Marshall amplifiers. A high purity ceramic substrate is assembled with interference fit end caps to which are welded the termination wires.

The Psvane 6L6GB is a high quality beam power tetrode with an octal base. The Psvane 6L6GB is noted for its outstanding sound and is an excellent choice for both guitar and stereo amplifiers. The clear top construction is similar to the classic short bottle 6L6 tubes made by GE and RCA. The 6L6GB is similar to other 6L6/5881 tubes but with a maximum plate dissipation of 19W. 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.

Filament type triode power amplifier. It is designed for service in the output stage of audio amplifiers where high output and low harmonic distortion is desired.

Medium-mu twin triode designed for use as a voltage amplifier or oscillator.

Filament-type pentagrid converter designed particularly for use in low drain battery-operated equipment. This tube will operate satisfactorily with only 45 volts B supply.

Filament type triode power amplifier designed for service in the output stage of audio amplifiers where high output and low harmonic distortion are desired. Its ratings and characteristics are similar to those of the 2A3 and 6B4G.

Genalex Gold Lion ECC81/B739 (12AT7) dual triode preamp tube with gold pins. Made in Russia. Original Genalex Gold Lion ECC81/B739 tubes are considered the best 12AT7 types ever made. They are also among the rarest types available. They exhibit a large detailed soundstage that is characterized by an expressive midrange, deep tight bass, and a smooth extended high end. The reissue Genalex Gold Lion ECC81/B739 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

Triple grid general purpose detector amplifier.

Pentode amplifier designed for application in power output stages of receivers

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.

Triple grid general purpose detector amplifier. With the exception of capacitance, its electrical characteristics are identical with those of the 6J7G and 6J7GT.

Beam-power pentode primarily designed for use in the power output stage of high-fidelity audio-frequency amplifier systems.

Sovtek 12AX7WB dual triode.

Consists of two dynamically coupled triodes and is designed for service in the power output stage of AC and storage battery operated receivers. All necessary biases are supplied internally

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

The JJ Electronic 5U4GB is an excellent choice for an economically priced tube rectifier. Used in many Hi-Fi and guitar amplifiers, JJ delivers a robust and solidly built tube. This full wave rectifier will work in any 5U4 application.

The JJ Electronic 5881 is very similar to the 6L6GC but with a plate dissipation of 23W rather than 30W. Another physical difference is the shorter bulb. These tubes have a soft and balanced response that sounds great in both guitar amps and hifi equipment. The JJ 5881 will work in any amp that uses 6L6 tubes.

Half-wave high-vacuum rectifier designed for use in a-c/d-c receivers. The heater is tapped to permit operation of a panel lamp.

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.

New Old Stock (N.O.S.) tube. 25CD6GB is identical to the 6CD6GA except with different heater ratings. Beam power tube, octal base.

Beam power tube - high power sensitivity RCA "Dark Heater" with 12 to 15 volt range.

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.

The 6GM5 is an audio power amplifier
