[. . . ] [. . . ] Several accessories appeared progressively: plates and cores CCIR or NAB and a kit to use loops of magnetic tape It left then a model 38 and 19 cm/s CCIR, generalized in the studios and, of course, most interesting, there is a model with 4 tracks stereo (1/4 of track) and a model Dolby B; to avoid both!It is necessary to point out that the Revox A77 is a "dual track" and not a true stereo machine (the difference is in the precise width of each track and the distance between these tracks).
