- Drive construction without belts and slipping clutches
- Another model of the same series:
- Revox B 710 MK II with Dolby C (lt Revox website).

Test reports[edit]
- Stereoplay 9/1982: "Spitzenklasse II" (same group as the legendary Nakamichi Dragon; best classification of cassette decks by Stereoplay at the time; for tape machines "Spitzenklasse I").
