Studer Revox A-77 stereo tape recorder
This stereo tape recorder came from the company founded in Zurich, Switzerland in 1984 by Willi Studer. The A-77 was launched in 1967 and has sold over 400,000 units - very strong sales for a piece of high-end audio equipment. It has three motors, can play at 7.5 ips (inches per second) and 15 ips (19 cm and 38 cm per second respectively). There are three tape heads, for erase, recording and playback. Separate pre-amps for each head, and separate record and replay circuits permit full-source tape monitoring.
