Marantz PM-8mkII 255,000yen(around the 1980 time)

The Integrated Amplifier of the high end to which the polish was further applied based on PM-8 and which raised completeness.

In order to reduce a TIM, the Low-TIM design original with a control part is performed with the power part.
Furthermore, in order to banish the sound dry area at the time of the high output in AB class etc., the newly developed super high ft transistor of ft90MHz is adopted as all the power transistors of four one side channels and a parallel push pull interconnection, and switching distortion is reduced by this.

The DC stream-composition MC head amplifier of the low-noise FET adoption which arranged the pair property with the equalizer of DC stream composition with the output stage by the three-step hardwired connection SEPP is carried.
The cartridge loading selector is carried and the performance of a cartridge can be pulled out more.

The try tone control which can be adjusted by low-pass, a mid range, and each of a high region is carried. Furthermore, a still finer sound field correction is possible for low-pass and a high region by the change of a turnover frequency.

Two record selectors which can carry out the independent sound recording of the source which is different to the two decks are carried.
It is also possible to add a tone correction at the time of a sound recording.

The power transformer carried the pre and the thing only for power, respectively, and also the reliable custom product was adopted as the output transformer and the capacitor with the right-and-left independent stream composition with large capacity, and the failure of the regulation is prevented.

A coaxial cable is adopted as the shielding-wire fraction of a signal system treating a low voltage, and the oxygen-free-high-conductivity-copper line is adopted as other lead wire of all the.

The original energy sensor type is carried in the protection network, and a power transistor is protected, without interrupting a music play.
