Maintenance product with 42 transistors, switches, and volume disassembly contacts polished! A stereo premain amplifier developed by inheriting CA-1000 technology. It is an impressive model with a Yamaha look and a straight tone with a glossy high frequency. Even though it's an old model, it doesn't feel that the range is narrow and it makes a youthful sound. You can see a feeling of use, such as appearance, dullness, small scratches, etc. (Kobayashi Hitoshi)
