  • Columbus 44 Console

    7-Valve (including magic eye) superhet with RF stage AW receiver. 10.5-inch permanent magnet elliptical speaker.

    Part of a small range of models, designed at the time using a 'modern' permanent magnet speaker (as are still used today) rather than Radio Corp's 'old faithful' electro-magnetic speaker design that had served them so well for so many years (indeed those EM speakers still sound fantastic today).  This model's design introduced several other new features for Radio Corp including a tuned choke power supply (allowing the use of smaller filter capacitors) and the 6V6 output valve replacing the 6F6 that they had used for so long in so many models.

    Manufactured by Radio Corporation Of New Zealand Ltd for Columbus Radio Centre Ltd.
