Sony TC-350

The Sony TC-350 is a notable reel-to-reel tape deck from the mid-to-late 1960s (typically released around 1966). It holds a special place in Sony's lineup because it was one of their early consumer-level decks to offer a three-head system, which was a significant feature for audio enthusiasts at the time.

It was designed as a "Tapecorder" system, often featuring a wood base, and was one of the popular, reliable solid-state (transistorized) decks that helped define consumer hi-fi.
