Sony CFS-F70

One of the most rare and exotic Sonys, this model was the heaviest and most feature-packed of any boombox of its size. It measures only 476 x 153 x 180 mm, yet it carried a suggested price of 128,000 yen!! It has 10cm speakers with huge magnets, and iron reinforcements inside the front case. It has BTL amps that produce 6.5 watts per channel by the Japanese EIAJ/DC industry standard. That is huge for a mini!!
