A four-page leaflet, slightly smaller than A4, in landscape orientation, introduces SONY components: the TA-1055A integrated amplifier and the ST-5055A AM/FM tuner. The leaflet assembles the Listen-7 system with ULM-10 speakers, the TC-2130A cassette deck, the PS-5100 player system, ECM-250 and ECM-2250 microphones, and the SU-3000 rack. It names direct coupling, a quasi-complementary circuit, and a symmetry SEPP circuit for the TA-1055A, plus a JFET input stage, FET mixer, and solid-state filter for the ST-5055A.
