A compact control amplifier with a built-in non-feedback CR phono amplifier. It can also be used as a line selector, and the sound is of high quality as a phono amplifier. The thick mid and low frequencies don't make you feel small. The exterior has dullness, abrasions, etc. (Mizusaki Ryo)
Maintenance information: 2023.6.18 Maintained (I replaced it with a custom-made 4-volume volume product, there are solder cracks in other boards, and some solder repairs have been made. (I'll check that the other input/output connection sounds, and the other INPUT switching SW knobs seem to be slightly rattled, but there is no problem because the fixing screws are loose and the SW shaft body is rattled)
Accessories: none
Main specifications: Non-feedback CR type phono amplifier line input 4 systems phono input MM/MC balanced input/output available W136 x H133 x D353 mm 6.3 kg
