Description
Revox B750 MK II amplifier. Classic Vintage. Fully revitalized.
Studer is a Swiss designer and producer of audio equipment for recording studios. The company was founded in Zurich in 1948 by Willi Studer. Reel-to-reel tape recorders first produced by Studer were called Dynavox. Dynavox 100 was succeeded by the first Revox recorder, the T26 from 1952. The name Revox was adopted as the brand of commercial “reels” in 1951, while professional studio equipment kept the name Studer. In 1990, Willi Studer sold the Studer Revox Group to Motor-Columbus AG. One year later, Motor-Columbus split the company into Studer (Pro), Revox (HiFi) and a production division. The extensive reorganization ended with the sale of the Studer Group to Harman International Inc. in March 1994.
In addition to the highest quality reel-to-reel tape recorders, the Revox brand also encompassed valued cassette tape recorders, CD players, amplifiers and tuners – most often based on Studer?s studio designs.
Revox B750 MK II is a transistor model, often compared to good tube amplifiers thanks to its warm and clean sound and exceptional playback quality that were created by the best Studer engineers. It is also worth noting that the designers took care of a simple, elegant, and at the same time original design of this iconic device.
The enclosure has been cleaned and revitalized. Side boards made of American cherry wood were added. The wood finish is Chinese oil produced from natural oils. The wood is extremely nice to the touch. Potentiometers in perfect condition. The device has been fully reviewed and serviced.
