Listen to your favourite music from any music device including your smartphone, PC or CD players. We have adapted this device to emit short-range AM audio to your AM tube radios. This is a new item that we have never announced before that could be a real revolution for owners of AM tube radios. Stream your favourite music from your phone or computer via Medium Wave and listen to it through your AM tube radio. One of our costumers said: "Most of us who enjoy the old MW tube radios use a Bluetooth connection into the high impedance “phono” input of our receivers. The idea of actually “tuning in” the audio source is a really better solution and makes the experience more authentic" (Richard Winslow, USA) Owners of older AM radios could only receive from the very few radio stations that still operate in AM band, but now they can stream from their favourite music player! Batteries not included. They work either with 4 x AA batteries or a power source.
