This is a 7-row varicon-type FM tuner! It is a model based on black from the L series, not the KT series! It takes over the good parts of the KT series, such as good sound quality and sensitivity. The sensitivity is good, and the sound quality is not sharp, and it is comfortable to listen to with a soft sound. The size is also thin, so there is no problem with the installation location. There is a repair mark on the right side (Shota Sasaki)
