It’s more than 30 years since the last Revox reel-to-reel tape recorder was made, and this glossy guide documents the Swiss brand’s range from 1949 to 1993. Conceived as a manual for historian audiophiles and fans of the format, it documents all 25 Revox models over 240 pages, illustrated with more than 400 previously unpublished photographs. Available in pocket and full-sized softback and hardbook versions with English and Italian text, prices range from £63 to £136. Click here for more.
