The complete revision of the F36 to give the Revox G36 led to the culmination and final stage in the development of tape recorders with valve electronics. The replacement of the “green series” with a more modern “grey/blue” was more than just a facelift. The device was enlarged so that it could also be used with tape reels measuring up to 26.5 cm (10.5″). For tape reel operation, a synchronous motor was used for the very first time, which guaranteed an absolute speed within very tight tolerances. With a solid integral casting, the new capstan motor, together with the pinch arm and recording head, formed a unit with particularly long-term stability. In the tape drive, a contactless photoelectric tape end switch was ultimately implemented over the course of the G36 series. To achieve even tape reeling during quick rewinds, the unwinding spool was braked slightly with a counter-tension on the winding motor. The amplifier electronics remained almost unchanged as compared to the Model F36, but with one important exception: modern illuminated indicator instruments were used as peak programme meters, called VU meters (volume units), which also allowed one valve to be eliminated. When the last Revox G36 left the production line in Regensdorf, Switzerland in 1967, one of the most successful product series in the history of the company came to an end.
