Put a period in Radio! It seems like absurd nonsense, but it is....a simple Subscriber Loudspeaker that served as the end point in radio transmission lines. A simple design, but how much interesting can be found in it. The fact that after a 220-volt outlet this device continued to work is a paradox in itself. And how many radio-killer circuits used transformers from these devices. Radio! Period. ATTENTION! You are on an auxiliary technical channel, here various previews, texts, names and slogans and other bells and whistles for the main channel are being worked out! Please take into account, understand and forgive! ;-)
