Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube amplifier (valve amplifier in British English), a vacuum tube-based audio amplifier. [1] At first, the concept of tube sound did not exist, because practically all electronic amplification of audio signals was done with vacuum tubes and other comparable ...
A valve audio amplifier or vacuum tube audio amplifier is a valve amplifier used for sound reinforcement, sound recording and reproduction. Until the invention of solid state devices such as the transistor , all electronic amplification was produced by valve (tube) amplifiers.
Vacuum tube audio still finds a niche market within the audiophile community. Tube amplification is known for its warmer sound, and known to bring out the fullest of analog media, when compared to solid state audio components. [ 2 ]
One of the key connections between this far-eastern attitude towards the SET, and the west was Jean Hiraga, longtime editor of l'audiophile in France (and in French). [ 2 ] A very extreme example of an almost "zen" or "poetic" approach to amplifier design in the far east—very different from the Western engineering-led approach—is the work ...
JJ Electronic was founded in 1993 by Jan Jurco, using the old Tesla machinery for the manufacture of vacuum tubes. Eventually, JJ Electronic started to produce its own line of vacuum tubes and electrolytic capacitors, mainly targeted at high-end audiophile and guitar amplifier applications.
The tube is popular in hi-fi vacuum tube audio as a low-noise line amplifier, driver (especially for tone stacks), and phase-inverter in vacuum tube push–pull amplifier circuits. It was widely used, in special-quality versions such as ECC82 and 5814A, in pre-semiconductor digital computer circuitry.
The EL84 is a vacuum tube of the power pentode type. It is used in the power-output stages of audio amplifiers, most commonly now in guitar amplifiers , but originally in radios. The EL84 is smaller and more sensitive than the octal 6V6 that was widely used around the world until the 1960s.
In electronics, the 300B is a directly-heated power triode vacuum tube with a four-pin base, introduced in 1938 by Western Electric to amplify telephone signals. It measures 6.4 in (16 cm) high and 2.4 in (6.1 cm) wide, and the anode can dissipate 40 watts thermal.
