Teac A-450 (early 1970s)

Name: Teac 450
Brand: Teac

The Teac A-450 was an early top-tier cassette deck. TEAC introduced it while working to push the cassette format beyond convenience dictation and into serious high-fidelity territory. High Fidelity (September 1973, p.43) reviewed it at a list price of $399.50, a lot of money then. The magazine gave dimensions of 17⅝ by 6⅛ by 9⅛ inches, in a wood-and-metal case with Dolby B noise reduction.

Performance was the 450's headline. High Fidelity's lab measurements confirmed mid-range total harmonic distortion below 1%. Wow and flutter was just 0.07% in record/play mode, and the magazine noted that only the $1,100 Nakamichi matched it among the decks they had tested up to that point. Frequency response was described as "very fine" and Dolby tracking as unfaultable. The low wow and flutter came from a newly designed transport drive system with a capstan machined to a critical tolerance of 0.15 microns, as TEAC's own advertising highlighted (HiFI-Stereo, April 1974, p.39).

TEAC also positioned the 360S as a more affordable sibling, with identical transport performance, fewer features and a lower price. The 450 carried a two-year parts-and-labor warranty, which was unusually generous for the period.

Specific production years are not documented in surviving sources. The review and advertising record places the model in the 1973-1975 window.
