Studer Revox G3 36 Tube Tape Recorder

The Revox G 36 was the crowning glory in the development of tube-based tape recorders. For the first time, reels with a diameter of 26.5 cm could be used. The Revox F36 and its predecessors could be operated with reels with a maximum diameter of 22 cm. The Revox G 36 was the first device to use a synchronous motor as a sound motor. Studer Revox launched three versions of the G 36 with minor modifications. The product was extremely successful until production was discontinued in 1968.

The Revox G 36 had two types of mechanical tape end switches. A microswitch was used up to device number 36,500. From device number 36,501 to 58,000, a sensor lever activated gold-plated wire contacts. From serial number 58,001 onwards, the tape end was detected optoelectrically. There is a light guide through the right deflection roller and a photoresistor in the standing bolt. Long rods for the potentiometers and rotary switches ensure short signal paths.
