  • Western Electric Co, Low-frequency Amplifier, Reg No 3123

    It was used with a Western Electric loudspeaker and any good Valve Detector Set for amplifying radio telephony speech or music.

    The Amplifier is specially designed and is contained completely in a polished mahogany case constructed on simple lines and is fitted with a switching key, which enables either one or two valves to be used as required without a change in connection. The key in its central position disconnects both valves.
