Akai - AT-52L Tuner

Akai AT-52L quartz synthesizer AM/FM/LW stereotuner, built in Japan (circa 1987–1989). Technically in 100% functional condition with fast frequency locking and interference-free reception; visually in neat vintage condition with light signs of use consistent with age. For enthusiasts of thoughtful radio technology from the late 1980s, the AT-52L offers a very stable digitally controlled tuning system. The core is formed by a quartz-controlled PLL synthesizer (Phase Locked Loop), which locks in stations without drift. Unlike the standard AT-52, this 'L' version provides three-band reception: FM, Medium Wave (MW), and Long Wave (LW). In terms of sound, the tuner delivers a clean, balanced and quiet stereo image with low background noise and excellent channel separation. The front panel features a bright display with a digital field strength indicator (signal meter), direct frequency access and memory for 16 preferred stations. A convenient feature is the switchable IF Band (Wide/Narrow): in the 'Wide' position, the tuner delivers maximum audio quality with minimal distortion for strong signals, while 'Narrow' provides high selectivity to receive closely spaced weak stations interference-free.
