Power Amplifier


The limited edition CSCP-275L has two significant features.     Firstly, it is composed with a lot of New Old Stock component which was  manufactured in the 1960's for reproducing pure analogue sound. In order to avoid  the degradation of sound quality, none of the semiconductor devices were used on a  signal path. Diode for rectifying AC current is only semiconductor device used in this  amplifier.   Secondly, the CSCP-275L power amplifier has a very unique and special cosmetic  design. It   has circuit boards to mount the passive devices on the top while the  conventional tube amplifier has components mounted underneath the chassis. The  tubes are also mounted on the top of chassis. However, differently from conventional  tube amplifiers, the top cover of this CSCP 275L is made of glass, which enables to  look inside of the circuit board from top of the amplifier (Design patent 30-0710629).  In addition to above features, this amplifier uses point-to-point wiring method. Most of  all tube amplifiers recently made use printed circuit boards for reduced labor cost. As  a result, it becomes very difficult to replace faulty components for repairing and the  printed circuit board may be damaged by poor repair. Point-to-point wiring removes that  kind of worry.   The limited edition CSCP-275L tube amplifier is designed to be a reference amplifier for  the use of dedicated audiophiles. It carries 75W per channel stereo signal with using four "Gold Lion" branded KT88 beam tubes. A voltage gain amplifier is direct-  coupled from a cathode coupled phase inverter, which in turn drives the cathode follower to drive the output tubes. About 6db loop negative feedback reduces  distortion and achieves a sufficiently high damping factor to control the reactive load typically presented by high-performance loudspeakers.
