Description from the seller
The OPTONICA SM‑3000 (also known as SHARP - 3000H) is a high‑end Japanese vintage amplifier from the mid‑1970s, renowned for its warm and well contoured sound, solid power output, and robust construction. It stands out with its advanced architecture (multi‑transformer power supply, differential amplifier stages, sophisticated filtering) and elegant classic design and wooden sides.
The device has been tested and verified, everything is working properly. It has no modifications or other interventions.
Excellent optical condition, with a beautiful silver metallic front, a black metallic case (with just some minor signs of wear) and two beautiful original wooden sides. It is a vintage item that has been remarkably well-preserved, both visually and technically. Refinement, multiple settings and superlative sound fidelity - OPTONICA by Sharp, made in Japan.
