Our take on the Panasonic ST-373 Synthesizer Tuner AM/FM Stereo Digital Quartz Lock Tuner

The Panasonic ST-373 is a digital synthesized AM/FM stereo tuner from Panasonic's component hi-fi era. It uses quartz-lock electronic tuning with a digital frequency display, preset station memory, and both automatic and manual tuning modes. It suits someone building or restoring a vintage stack of separate components who wants stable, drift-free FM stereo reception without a modern digital radio. Against newer tuners it lacks RDS, DAB and remote control, but its quartz lock and preset memory put it well ahead of older analog dial tuners. Units sold as refurbished are described as tested, cleaned and with worn parts replaced.
