  • Notes
  • "Undoubtedly the crowning achievement of this season’s distinguished range of K B All-Feature Radio Receivers, the K B 660 is supreme among modern receivers as an
    example of technical and artistic excellence. Possessing many advanced features and refinements, it satisfactorily fulfils the requirements of the critical listener who is prepared to pay a little extra for the very best that modern all-world radio can offer.
    The unusually large output of the KB 660 Superhet, 8 watts-besides providing an ample margin of power for ordinary domestic reception, makes the receiver particularly suitable for special purposes where great volume of brilliantly realistic reproduction is required."
