Kenwood TK-88 (c. 1967–1969)

The Kenwood TK-88 is a solid-state AM/FM stereo receiver from the late 1960s. It belonged to a line that also included the TK-66 and TK-55. It used FET (field-effect transistor) circuitry and was rated at 90 watts - likely total output, though the period sources are not more specific. HiFI-Stereo (March 1968, p.37) listed it at $289.95. Another ad called it a “popular priced luxury receiver.”

High Fidelity (July 1968, p.27) tested the TK-88 and measured its IHF usable sensitivity at 2 microvolts. The magazine called it “one of the better receivers we have tested.” The same review noted harmonic distortion rated at 0.6% (context suggests this is at or near rated output). Audio (February 1969, p.49) ran a Kenwood advertisement that praised the receiver’s “crisp, clear” speech and music reproduction, and its “dependability, reliability and quality.”

Features included automatic FM stereo switching, multiple convenience switching options, and circuit protection - all common Kenwood hallmarks of the era.

Beyond the magazine coverage, little else is documented about the TK-88.
