Commentary

A pre-main amplifier employing a 2-transformer system with separate transformers for the power and pre-parts.
In addition, a three power supply system has been adopted in which the power section is a constant voltage circuit completely independent of the right and left, and the power supply circuit of the pre-section is also separate.

It is equipped with a loudness contour.
