Revox B780 receiver. Classic Vintage. Fully renovation.
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 took their B760 digital frequency synthesizer tuner and their B750 mkII integrated amplifier, re-engineered them into what they called a “symbiotic relationship”, and created the B780. You would think that taking two components and melding them together into one box would require some sacrifice. But, Revox actually made some improvements to their tuner and amplifier circuitry when they designed the B780. They did this through the use of a microprocessor chip which made the switching functions far more efficient.
Revox B780 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 completely revitalized, potentiometers are in perfect condition, metal elements of the enclosure have been sandblasted and painted using the automotive wet painting technique.
The device has been fully reviewed and serviced.
