NAD 1150

The NAD 1150 appears in period documentation as a stereo tape deck, though surviving information on this model is thin. What the record shows: it was a 4-track, 2-channel stereo unit with two heads — erase and record/playback — and a hysteresis synchronous motor. Wow and flutter was specified at 0.07% (WRMS), and frequency response ran from 30–16 kHz (±3 dB, 30–15 kHz) with CrO₂ tape.

The model number appears alongside the similar NAD 3605 in specification listings from High Fidelity (January 1974, p.72), suggesting the two shared a common transport design. NAD's broader preamplifier advertising from the mid-1980s emphasized discrete-transistor phono stages across their lineup, but no equivalent design detail for the 1150's playback electronics has surfaced.

Beyond these specifications, almost nothing else is documented. Production years, original pricing, and any contemporary review coverage of the 1150 as a standalone product have not been located. If you have original paperwork, a service manual, or firsthand experience with this deck, the archive would welcome the contribution.
