Here's one I have not seen yet Yamaha TC-800D
Great deck, a real plus at any party back in the 70's, still sounds as great!
Designed by MARIO BELLINI
Here are some of what has being said about the 800:
"Like all of Yamaha's early audio units, this was a statement. It received many honors, museum exposure and praise.
The first TC-800 sported a High Filter and a Microphone switch ; the TC-800GL replaced these with a Dolby IC and a Mic/Line mixing function, received a Limiter switch and could operate with a DC 12V power source or with nine 3V batteries as well. A third version, TC800D, was an updated 800, with an added DIN connector, auto CrO2 tape compatibility and Dolby IC ; it eventually replaced both original versions." thevintageknob.com
"But the TC-800GL wasn't simply a radical set of clothes hiding a bog-standard cassette deck, because everything from the peak level meters to the power switch was designed for maximum effectiveness and ease of use. For the casing, Bellini eschewed fake wood in favour of a tough, durable plastic covered in finely applied dark charcoal neoprene. Almost like suede to the touch, the finish instantly endeared itself to the user, making the deck less 'machine-like'.
The transport's lightly pressured piano key controls were very slick in an era before cassette decks had solenoid operation, while its array of sliders for line and mic inputs, playback level and pitch were intuitive to use. Although sparsely turned out, the deck was packed with unusual touches to facilitate operation, including automatic tape-type switching, timer recording, memory stop and superb meters.
Competitors offered the customary excuse, "Things which look good invariably don't sound it", but the Yamaha's performance said it all. Fitted with a good Permalloy head and a precision servo-controlled transport the TC-800GL measured superbly by 1975 standards.
With chrome tape Yamaha quoted an impressive 15kHz at -3dB frequency response, and an excellent 0.06% WRMS wow and flutter. Even today, a well preserved example is capable of sparkling highs, deep bass and great image stability." HI-FI World UK
