This is a listing for an FM/AM tuner. I connected it to my amplifier and speakers to check FM/AM reception and sound output. The sound output was clear and stable, although this depends on the radio wave conditions and is subjective. This is an expensive tuner that cost ¥49,800 when it was released in 1972. The power cord shows signs of aging, but the main unit is in relatively good condition. The approximate dimensions are as follows: Width: 40cm, Height: 15cm, Depth: 32cm Please consider purchasing if you are interested.
