Maintained. A diatone preamp with a thick mid-range sound. The sense of extrusion in the low frequencies is also good, and the overall sound is energetic. Also, it is a unit with a full range of functions as a preamplifier, such as input gain adjustment and left and right independent tone control. The exterior has many scratches and dullness overall (Oikawa Tetsuji)
