Sony TC-330

The Sony TC-330 is a unique and comprehensive piece of vintage audio equipment, released around 1971-1972. It is most notable for being an integrated all-in-one stereo unit that combined two different tape formats: a reel-to-reel recorder and a cassette deck.

It was designed as a complete "Tapecorder" system, often including amplifiers and speakers housed in its detachable lid, making it a portable or tabletop hi-fi system.
