  • Bemerkung

  • The " 26 " Series receivers were scheduled for release in April 1935.

    Technical details of the ' 26 ' receivers are now available, and it is revealed that the reduction in prices has been brought about by the acceptance of a lower overall gain as compared with the "24" series. As the latter provided an ample margin of range for most people's requirements, the reduced noise level on distant stations in the new receivers is a point in their favor. The principal change in the circuit is to be found in the second detector stage in which a double diode is now used without the triode amplifier which usually accompanies it. The omission of amplification in the AVC circuit will affect the behavior of the set only for very large signal inputs, while on the LF side the reduced gain has made the heterodyne whistle filter of the A24 unnecessary.

    The cost has therefore been reduced by a decrease in the number and not in the quality of the chassis components. Other changes in the A26 include the extension of the medium-waveband down to 195 metres, the incorporation of the on-off switch with the volume control instead of the wave-range switch, and the omission of the gramophone jack. In connection with the latter, it is proposed to issue an instruction to dealers indicating how gramophone connections may be made when there is a specific demand for this feature.
