Maintained by the manufacturer in 2019. This is a SUN AUDIO preamp with an eye-catching bronze panel on the black face of the finished model. All transformers are custom-made by Tamura, and they are particular about being lead wire types without using printed circuit boards. They are dull in places, and there are scratches on the side panels (Kojima Yosuke)
