Yamaha TC-720B (where the 'B' stands for the black or "Black' version) is a high-quality, vintage 3-head cassette deck from the "Natural Sound" series, produced by Yamaha in Japan between 1978 and 1980. The model is known for its robust mechanical build quality and advanced audio features for that time. Because it is a 3-head deck, you can immediately listen to the actual sound quality on the tape while recording (switching between Source and Tape).

Heads: 3 heads (1x erase, 1x record, 1x play), presumably made of the hard-wearing Sendust material. Tape Support: Suitable for Type I (Normal), FeCr (Ferro-Chrome) and Type II (CrO2 / Chrome). Please note: this deck comes from the period just before the introduction of Type IV (Metal) tapes, so these are not supported.
