Reel To Reel Tape Recorder supplied with two adaptors Nab and two metal reels. Inspected by Revox Mania Luca Maria Olgiati. We give one year warranty.

The Revox A-77 is one of the most appreciated tape recorders for its extremely precise speed regulation, virtually zero wow and flutter, minimal noise, impeccable tape handling, and an extraordinarily wide and linear frequency response.

The Revox A-77 was designed to use low-noise Scotch tapes. However, some models may require more precise adjustment, particularly to optimize the frequency response, achieving reproduction unmatched for linearity and detail rendition. The recorder is equipped with numerous internal adjustments to accommodate the type of tape used, and its frequency response makes recordings incredibly natural, with reproduction almost indistinguishable from the original signal.

From a mechanical standpoint, the A-77 offers perfect tape handling with completely inaudible flutter, also thanks to the tension arm that further reduces distortion.

Regarding maintenance, the Revox A-77 is designed to be easily repaired, with all circuit boards modular and easily accessible. The service manual is clear and concise, making maintenance even simpler.

The Revox A-77 is still considered one of the best tape recorders on the market, offering unparalleled audio quality, perfect for those seeking a device that delivers professional performance.
