Marantz ST-8 (1980)

The Marantz ST-8 is an FM stereo tuner introduced in 1980 at a list price of $450. Not much else is on record. The tuner shows up in period equipment directories and spec databases, but little design history or contemporary review commentary has survived in accessible form. High-Fidelity (June 1979, p.65) includes the ST-8 in its listings of current models and accessories.

The measured figures are what is documented. Sensitivity is rated at 10.3 dBf, total harmonic distortion at a very low 0.08%, and signal-to-noise at 75 dB. Frequency response spans 30 Hz to 15 kHz. Output is provided at both fixed (0.6 V) and variable (2.4 V) levels, and power consumption is a modest 17 W.

Dimensions and weight are listed in some sources, but the figures weren't captured in the available record. No circuit topology, internal construction details, or production end date have surfaced either. If you own one and can fill in the physical details, the archive would welcome the contribution.
