A SET tube audio amplifier. A single-ended triode (SET) is a vacuum tube electronic amplifier that uses a single triode to produce an output, in contrast to a push-pull amplifier which uses a pair of devices with antiphase inputs to generate an output with the wanted signals added and the distortion components subtracted.
D+M Group, formerly known as DMGlobal and D&M Holdings, is a Japanese corporation that owned several audio and video brands. It was formed in 2002 from the merger of Denon and Marantz. [1] [2] It had acquired several other companies since that time. Prior to 2008, it was owned by RHJ International, which is associated with Ripplewood Holdings.

Using a double triode (typically octal or noval) to form a SET input buffer (giving gain) to then feed a concertina phase splitter is a classic push–pull front end, typically followed by a driver (triode) and (triode or pentode) output stage (in ultra linear in many cases) to form the classic push–pull amplifier circuit.
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. In the 1980s it began to be used increasingly by audiophiles in
It was suited only to a limited range of audio frequencies - essentially voice frequencies. [23] The triode was the first non-mechanical device to provide power gain at audio and radio frequencies, and made radio practical. Triodes are used for amplifiers and oscillators. Many types are used only at low to moderate frequency and power levels.
PABC80/9AK8 – High-mu triode, triple low-voltage diode (two on common cathode with triode, one with independent cathode). Noval base, used as an AF amplifier, AM detector and ratio detector in AC-powered post-war European AM/FM radios and TV receivers; identical to EABC80 / 6AK8 , 5T8, 6T8/6T8A , HABC80/19T8, UABC80/27AK8 and DH719 except for ...
