  • Notes

  • Same cabinet as Pye E/AC and Pye E/B but DC mains only, using 100mA series versions of the valves in E/AC (See CR/DC for a Pye DC mains only model of same era, but different appearance). The E/AC uses a single Pentode as Mixer/Osc (Frequency Converter) but the E/DC uses separate Tetrode Mixer  and Triode Local Oscillator valves.

    DC Mains only!  Chassis connects to mains! Gram sockets and Aerial  are only capacitor isolated.
