Detailed maintenance has been completed, such as fixing all soldering on each circuit board and exchanging the input volume. A class-grade power amplifier with 200W x 200W (6Ω) pure A class operation. This model was particularly popular among domestic power amplifiers at the time. Even when I listen to it now, it has a rich sense of volume, and the sense of scale is sufficient. The smooth high frequencies are also effective, and there is no fatigue and it is attractive. Exterior, paint deterioration, rust, dullness, scuffs, etc. can be seen (Kobayashi Hitoshi)
