The Sonys I have are much earlier, The FH-7 Mk. II, one in black (US), and one in silver (Canada). From what I've seen, the later FH's became rather watered down, with twin cassette decks, and only Dolby B (though the wireless remote is nice). The FH-7 Mk II has dolby C, rare among portables. The surrounds in these speakers are cloth, no rot here.
