Rolling Stone from 1982 with some info on speakers for your Walkman including the Numark I've posted and some of the Mura, Technidyne offerings. I love the Denon Headphones in the cassette case! And by the way, where can I get one of those killer jackets?
That's a great question and I don't know. Somebody pulled a patent on FM cassettes that might show more of how they are put together, maybe Toshiba? They never had an antenna but I thought AM might need one a longer one. My uber rare Toshiba RP-A2 AM Cassette Radio also does not have an external antenna. It's a heavy cassette, there's stuff in it but I have no idea how it works. They used a contact pin connector, I'm guessing there's some circuits inside the player, maybe some antenna?
Panasonic RQ-R3 from 1983, Rolling Stone Magazine. Anybody seen that cool FM tuner before? Please post photos if you own one!
Panasonic RF-H5 from 1984, I love this style headphone and would definately add to the collection if I ever find them.
From the summer of love 1984, Rolling Stone Magazine. Some cool insight into what the musicians were using including a FH7 for recording keyboards.
Old but good posted a video of the 1994 Dutch Sony catalog. I recall getting this catalog from the hifi store in town. There is a very obvious mistake in this one, from 48:30 onwards. Can you spot it in the screenshot below?
They put a DD9 picture next to the DX100 description. They're clearly talking about the DX100, as the DD9 does not have AMS function.
Indeed! Also AVLS, or remote control ('afstandsbediening') are not present on the DD9; none of the DDs had a remote.
Rolling Stone Magazine 1986, some mention of the new CD portables and a tiny blurb about the Marantz PMD 430 with DBX!
