    This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes.Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics.

  3. Peak inverse voltage - Wikipedia

    en.wikipedia.org/wiki/Peak_inverse_voltage

    For rectifier applications, peak inverse voltage (PIV) or peak reverse voltage (PRV) is the maximum value of reverse voltage which occurs at the peak of the input cycle when the diode is reverse-biased. [4] [5] The portion of the sinusoidal waveform which repeats or duplicates itself is known as the cycle. The part of the cycle above the ...

    en.wikipedia.org/wiki/EL34

    The EL34 is a thermionic vacuum tube of the power pentode type. The EL34 was introduced in 1955 by Mullard, who were owned by Philips. [1] The EL34 has an octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits; it was also designed to be suitable as a series regulator by virtue of its high permissible voltage between ...

    The typical valve using this topology in (rare) current commercial production is the 300B, which yields about 5 watts in SE mode. Rare amplifiers of this type use valves such as the 211 or 845, capable of about 18 watts. These valves are bright emitter transmitting valves, and have thoriated tungsten filaments which glow like light bulbs when ...

    This is a list of European Mullard–Philips vacuum tubes and their American equivalents. Most post-war European thermionic valve (vacuum tube) manufacturers have used the Mullard–Philips tube designation naming scheme.

  7. Valve amplifier - Wikipedia

    en.wikipedia.org/wiki/Valve_amplifier

    A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers in the 1960s and 1970s.
