This is a Sony premain amplifier representing the 70s. The sense of extrusion and thickness has increased, yet the Sony-like outline is an appeal not found in modern amplifiers. It's an amplifier that sounds better than it looks, and is a perfect match for vintage medium speakers such as the JBL4312 series. As for the exterior, there is a scratch on the top plate.

- description
- In addition to replacing 36 internal capacitors and exchanging 13 transistors, we also maintained every corner, such as dismantling and cleaning each VR, disassembling and polishing each SW! Sony's original sparkling mid-high range stands out. It goes well with jazz, etc., but the smooth, glittering expression of classical music is exquisite. The exterior is in a state where there is a feeling of use such as wear and tear over time.
