Sony ST JX22
A compact AM-FM stereo tuner from Sony's early 1980s lineup, with LED-assisted tuning and a thin front.
Overview
The Sony ST JX22 is an AM-FM stereo tuner. It has the minimalist, thin front typical of Showa-era Japanese audio gear. Tuning is simple. LED indicators guide you, and you adjust until the signal indicator turns green for the best reception. The unit has a 3-point LED signal strength display and a simultaneous switching stereo/mute function. It was designed to slot into the stereo systems of the period.
