It is the proposition that the history of vacuum tube amplifiers is inherited and new sense of values is created. The vacuum tube control amplifier, CL-88, was born as a result of challenging the proposition above. CL-88 has a radical body design with a central focus on 15-mm thick aluminum panel that conjures up a new era, and its innovative frame structure from which almost all components are hung is highly vibration resistant and secures high rigidity. The 2-step amplification NF type is adopted for a circuit. We have put in know-how accumulated for many years to pursue the potential of vacuum tube amplifiers because CL-88 has a simple circuit where wiring and component layout directly affect sound quality. We also offer the compact type vacuum tube phono amplifier, EQ-88, to analog fans to exploit the full attractiveness of analog disks by combination use.
