  • Notes

  • The Duophase 6 has been specially designed to give enormous daylight range, remarkable battery economy, simplicity of control, and a minimum of upkeep troubles.

    The sensitivity surpasses any set within its class and can compare more than favorably with receivers at double the price and twice the valve power.

    The chassis built, totally shielded wonder set actually consumes less battery current than most 2-valve sets (“B” battery 7 mA; “A” battery 0.4 A).

    Complete with a handsome two-tone Walnut cabinet, artistic escutcheon plate, aristocratic “Operadio” air column speaker, and high-grade accessories £37/10/-.

    Also available as a battery console.
