About the DA-F20
The Mitsubishi Diatone DA-F20 is a quartz-PLL-synthesized FM stereo tuner introduced in 1978. It features digitally displayed frequency tuning, stable station selection, and separate wide- and narrow-band IF paths for balancing sound quality and selectivity. Published specifications include a 30 Hz–15 kHz frequency response, up to 75 dB signal-to-noise ratio, and FM distortion as low as 0.05% in wide mode. It is an FM-only tuner; claims that it provides absolutely drift-free tuning or universally “top-of-the-line” performance should be treated as subjective rather than specifications.
