2022.6 maintenance completed. A rare preamp sold during the golden age of Macintosh. It is a McKinn preamp with a mild impression compared to the C33, etc., and has an orthodox expression with thick mid-range and well-balanced low frequencies. Equipped with an equalizer function and many input systems, this unit is easy to handle with simple operation. In addition to the exterior and paint unevenness, you can also see a feeling of use such as dullness, rust, scuffs, etc. (Kobayashi Hitoshi)
