Design
The TC-350 has a 3-head design with separate erase, record, and playback heads, so it can monitor off the tape while recording. The playback head is a Sony 2-micron unit. The preamp section is fully solid-state and uses 18 low-noise, high-gain silicon transistors. It has a binaural headphone jack and a dedicated volume control for sound-on-sound (S.O.S.) recording. A micro switch cuts transport power when the tape is fully wound. The deck works standing vertical or lying horizontal, and it has a DIN terminal and a tape counter. Besides stereo, it can also record 4-track mono.
