Explanation　
This preamplifier was created by thoroughly reconsidering the PL45 type, which was announced as the last vacuum tube preamplifier.
The result of analyzing famous overseas products has been incorporated, resulting in a finished product with a higher degree of perfection.

The equalizer circuit is a three-stage K-KNF type (a method in which NF is applied from cathode to cathode).
This configuration is also used in the Marantz 7 model, and the CL35 has particularly improved input resistance characteristics.

The NF type LUX method is adopted as the tone control, and the curved points can be switched at three high and low points.
In addition, the tone control can be skipped with the defeat switch.

The filter has 2 high-cut stages and 2 low-cut stages.

The output stage uses a cathode follower circuit, which has low output impedance and is a stable circuit that is not easily affected by fluctuations in power supply voltage.

It is equipped with a socket for a step-up transformer and is also compatible with MC cartridges.

All CRs used internally are attached to printed circuit boards, and the layout is symmetrical with independent boards for each channel.
In addition, vacuum tubes can be easily inserted and removed by simply removing the protective board on the back.
