Z – Vacuum full-wave rectifier (dual power diode with common cathode) Following digits: model number and base type For signal pentodes, an odd model number most often identified a variable-mu (remote- cutoff ) tube, whereas an even number identified a 'high slope' (sharp-cutoff) tube

The 6AK5 vacuum tube is a miniature 7-pin sharp-cutoff pentode used as RF or IF amplifier especially in high-frequency wide-band applications at frequencies up to 400 MHz. It was developed by Bell Labs / Western Electric and used extensively as an I.F. amplifier in World War II radar systems. The tube is notable for its extremely fine grid, and ...
The transmitting tubes TT21 and TT22 have almost identical transfer characteristics to KT88 but a different pinout, and by virtue of their anode being connected to the top cap have a higher plate voltage rating (1.25 kilovolt) and a higher power output capability of 200 watts in class AB1 push–pull.
The KT90 is a vacuum tube used in audio applications. Typically, it is used in hi-fi or electric guitar amplifier applications. KT90 was developed by Elektronska Industrija Niš (EI). KT90 is designed by Blagomir Bukumira, a leading engineer at EI.
The 6V6 is a beam-power tetrode vacuum tube. The first of this family of tubes to be introduced was the 6V6G by Ken-Rad Tube & Lamp Corporation in late 1936, [1] with the availability by December of both Ken-Rad and Raytheon 6V6G tubes announced. [2] It is still in use in audio applications, especially electric guitar amplifiers. [3]
Later thermionic vacuum tubes, mostly miniature style, some with top cap connections for higher voltages. A vacuum tube, electron tube, [1] [2] [3] valve (British usage), or tube (North America) [4] is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
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 ...
