This is a 1960s Sony TC-200. It's a Reel-to-Reel tape player & recorder with stereo sound, and microphones included. The early models released in 1963-1966 were tube-based, while those made in 1967 onward would most likely be solid-state.
It plays 3 3/4 & 7 1/2 reels with two speed settings. While not the most versatile reel to reel, they are fairly inexpensive, stylish, straight-forward, and portable. The low cost and sizable supply online make these a nice start to a reel-to-reel collection.
