panasonic Technics sa 5800 solid state receiver from the Japanese Golden era 1970s

The Panasonic SA-5800 (also known as the National Panasonic SA-5800) is a vintage solid-state AM/FM stereo receiver manufactured in Japan between 1971 and 1972. It is recognized by collectors for its "tank-like" build quality and warm, pleasant sound profile. 


Designed to faithfully entertain your ears, this new receiver highlights all of the exclusive National Panasonic features; direct coupled ITL-OTL-OCL amplification circuitry and newly developed differential amplifier circuits reward you with exciting distortion free audio power.

Two highly sensitive 4-pole (MOS) field effect transistors, a linearly variable 4-gang FM capacitor, and a costly monolithic IC in the specially built MPX circuit will gratify your growing need for selectivity in today's crowded FM world.

Wider frequency response, higher damping factor with lower distortion and noise level, and superb, clear output signal all add up to incomparable stereo enjoyment.

The skilfully designed station targeting system, bolstered by highly sensitive tuning circuitry, makes the SA-5800 the most advanced stereo receiver available today.

The well-bred child of a close-knit family of electronics wizards, this sensitive instrument effortlessly meets the highest standards.
