McIntosh C-28
The C-28 was a McIntosh stereo preamplifier of the mid-1970s. The period press makes that clear, though almost no factory documentation has survived in the Archive's records. Audio (November 1976, p.66) reviewed it and singled out a couple of uncommon features: a "presence" mid-frequency emphasis control, and a tape input facility the reviewer said hadn't been seen in some time. The same magazine's test report (p.74) documented the tone-control range, the loudness-compensation response, and the high- and low-cut filter responses. That is the familiar McIntosh control complement of the era.
Beyond that review, the public record thins out fast. A classified ad in Audio (October 1980, p.148) listed a used C-28 at $390, alongside an MR78 tuner. No production years, original price, or full specifications are documented in the sources available to the Archive. If you own a C-28, or have an owner's manual, brochure, or service literature, the Archive would welcome the details.
