DENON PMA-915
33,000yen(around the 1988 time)

Description
 
The thin Integrated Amplifier which adopted simple straight composition.
The output of 50W+50W (6ohms) is realized by adopting a power transistor with large capacity as the last stage.

The tone control circuit is adopted.

Six audio inputs (it is an included about Phono MM) and two speaker outputs are carried.
