A vacuum tube premain amplifier from Oto Kobo, a manufacturer in Kanagawa prefecture. Deluxe type that has been changed to a bass boost function and a gold-plated SP terminal. I tried playing it at the store, but it sounds more than the size, and there is a sense of volume in the low frequency without bass boost, and the impression is that the resolution is exceptionally high compared to old vacuum tube amplifiers. It is also recommended for getting started with ball amplifiers and sub units. You can also enjoy the beautiful vacuum tube lighting function by appearance (Shota Sasaki)

A single amplifier using 6L6 as the output tube. The first stage is 6N2. It comes with a volume and input selector. Both inputs are line-only. There is an LP notation on the back, but there is no phono equalizer in it. When a CD is connected, there is no noise even if it is set to full volume, but if it is close to full volume in an open state without connecting it, noise will occur. It's currently sounding well, but since it's cheap, it's currently sold without a guarantee (Yasuhito Koshihama)
