DK92 / 1AC6
Description | The DK92 is a miniature heptode frequency changer for use in dry battery powered radio receivers. Domestic long and medium wave receivers would have this as the mixer to produce a 455 kHz IF from the incoming signal. It can be used with a separate oscillator, but was probably designed as a self oscillating mixer, in the manner of other pentagrid converters. |
