DENON PMA-300V
44,800yen(around the 1987 time)

Description
 
The Integrated Amplifier which aimed at formal playback of CD.

The power-source part adopted the original pure dynamic power source, and the toroidal transformer of 160VA is adopted as a transformer.

Circuit composition has achieved the reduction in distorted, and low noise-ization aiming at the simple & straight thoroughly.

MC/MM equalizer amplifier is built in.

The Subsonic Filter and the tone circuit are carried.

The input selector by an electronic switch is adopted.
