The CL-38uC uses SRPP (Shunt Regulated Push Pull) circuitry for all stages to achieve the highest sound quality possible.A genuine phono equalizer is included, the MC-low and MC-high impedance (gain) inputs each have independent MC transformers and are selectable using the MC impedance lever switch.Tone controls enable the listener to fine tune the sound quality.Refined exterior design and newly added balanced inputs make this vacuum tube control amp a new standard for its generation.
