A4 staple-bound booklet, 12 pages, with one six-page fold-out spread - SANYO’s catalog for December 1978 covering the REC boombox line and PULSAR pocket radios. The cover features the flagship MR-X900, a massive stereo boombox at 66.4 cm wide, which SANYO promotes through a “Compo in one” spread: five separate internal sections (Recorder, Deck, Amp, Speaker, Tuner) - essentially a component system in a single non-separable body. The top REC model - the MR-9550 STEREO QUARTZ (¥62,800) with LCD display and quartz stabilization - competed directly with the best Japanese boomboxes of the era. The PULSAR series - two ultra-thin (12.5 mm) pocket radios, PULSAR 01 and PULSAR 02 - gets its own dedicated page inside the catalog.
