Marantz PM-88aSE 90,000yen(around the 1994 time)

Description
 
The Integrated Amplifier which considered SE concept of MACRS tune-up thought, and aimed at higher level based on PM-80a.

The toroidal transformer is adopted as a power-source part. Thereby, an oscillation and an occurrence of leakage flux are stopped to the minimum, and electric coloring to a music signal is suppressed.
Moreover, a transformer case is filled up with the mixture of a resin and an inorganic substance, and the vibration proof system and the heat-dissipation effect are raised.

The copper plating is given to the chassis and the influence of a RF is suppressed by stopping the impedance to a RF lower than an internal wiring.

A top plate is 3 times [ usual ] the thickness of this. This is suppressing that an internal electronic part vibrates.
Furthermore, it is considered as the structure strong against an oscillation of the interior or the exterior by the die-casting side panel which fixes both sub-s firmly.

The 4-unit active volume which prevents a failure of S/N at the time of a real using is adopted.
Moreover, devices, such as a using of the knob of the aluminum Naked material which secures exclusion and the high stability of a tone control, are given.
