  • Remarques
  • Junior Eight is an amplified 3‑speed record reproducer, hand‑built and marketed “for the connoisseur”, intended for schools, home, clubs and institutional use. It uses a 5‑valve push‑pull amplifier feeding a 10 × 6‑inch elliptical loudspeaker, with automatic record change and speed control. The unit was offered in multiple cabinet finishes and motor options, reflecting Portogram’s mid‑1950s high‑fidelity line.

    Advertised in The Gramophone, October 1954, p. xlix, as a high‑quality record reproducer “truly worthy of the finest recording”, supplied to government departments, schools, education authorities and clubs. The mention of eight models suggests variants sharing the same chassis but differing in cabinet finish, motor type (Garrard/Collaro) and AC/DC supply.
