  • Kilodyne Four 1934 AC-powered, TRF Receiver sold as kit primarily designed for shortwave reception, with optional (2,5" vertical plug-in type) coils also MW.
    Metal chassis with an attached metal front plate.

    The receiver is very similar to the battery model except that provision has been made for fitting A.C. valves with the extra centre terminal and a tapped volume control supplying 15 volts negative bias to the output valve and variable bias from 0-15 volts to the variable-mu S.G. valve. There are also two extra resistances and a Humdinger* for controlling hum. The general mounting of the parts and wiring details are almost identical to those described for the battery model and these should be carefully read.

    There is a slight variation in wiring up the heater leads between the valves, together with leads to the Humdinger should be twisted together which reduces radiation and prevents hum.

    *Humdinger potentiometer acts as a virtual centre tap for non-center-tapped heater transformers, reducing AC hum in the AC valve amplifier.
