Retro 1970s, disco vintage Sansui dual deck tape player. Sansui made the D-70BW from 1970 through 1979. This player is marked "Stereo Double Cassette Deck" and "Computer Logic Control - Auto Level Control". This tape player is marked as a Dolby system and for high speed dubbing of cassette tapes. It measures about 17" long, 8.5" deep and 5" high. We hooked this up (through a stereo amplifier) and both tape decks work fine.
