SHARP Optonica SM 3000 Stereo Amplifier


Optonica was the high-end brand of Sharp in seventies.

The Optonica SM-3000 presents full features: preamplifier outputs, phono 1 attentuator -6dB, for phono 2 three-stage impedance matching. Bass/treble variable turnover control. Lowpass and highpass filters and -20dB muting adjustment.

An underrated amplifier that can compete with major brands like Sansui, Pioneer, Sony, Marantz & co.

The 45 watts per channel integrated amp is unusual solidly constructed for long life and guarantees fun for the vintage amp owner.
