A4 leaflet from Standard about one model, the SR-T137FJ - a portable boombox with FM/AM radio and a built-in cassette deck, 13 transistors, 800 mW output, 205×166×68 mm body, running on four UM-2 cells or a mains adaptor. Bundled with a dynamic microphone with remote transport control and a monitor switch that lets you keep listening to the radio while recording onto tape. Standard Radio Corp. was a Tokyo-based Japanese radio maker that entered a manufacturing partnership with Marantz / Superscope in 1966 and was renamed Marantz Japan Inc. in 1975; the SR-T137FJ belongs to that short window when the brand still went by its own name.
