A3 sheet folded in half, covering the SHARP GF-308SB and GF-308ST “The Searcher 308” - the first Searcher boombox with metal tape support, October 1979. The cover leads with “話題のメタルテープが使える” (finally, the talked-about metal tape), and the inside spread explains why it matters: a dedicated recording head, ITL-OTL amplifier circuit, and an upgraded APSS-XL (Auto Program Search System) that lets you skip 1, 2, or 3 tracks in one press. The back page has a connection diagram and a full list of optional accessories. Both color options - black GF-308SB and silver GF-308ST - at ¥57,800.
