JUST BACK FROM MY TECH FOR A SERVICE. AMP IS GREAT CONDITION AND SOUNDS GREAT. THE UNIT IS NOT PERFECT CONDITION BUT I WOULD SAY 8/10. THE FACE IS NEAR PERFECT BUT THE TOP EDGE HAS A FEW NICKS WHICH I TRIED TO PICTURE. Marantz PM-5 Description   The Integrated Amplifier which can switch a pure Class-A and AB class. In addition to pure Class-A 20 W/ch, the change of AB class 80 W/ch is attained. And in order to raise the quality of AB class even to the level of a pure Class-A, the high speed high fT transistor which took high high region cut-off frequency with 90MHz is adopted as the power stage. Switching distortion which is a fault of AB class is banished to a limit. In PM-5, it has a whole page perfect push pull DC amplifier stream composition that TIM distortion should be banished from all the corners in amplifier, and a nakedness property is improved. Even if it does not apply a lot of NFB, the TIM and the static characteristics are improved. In order to raise the operational stability of a power transistor, a newly developed heat-pipe scheme is adopted as a heat-dissipation organization. Since heat is drawn out of a circuitry and it cools by a radiator, a transistor can be arranged in an ideal location and simple-izing of a circuitry and a Low-noise-izing are raised. Moreover, the mass capacitor developed for audios and the powerful power transformer which was filled up with the special resin, took heat-resistant measures and was miniaturized are adopted as a power-source part. Especially a phone amplifier block is the low distortion and high S/N ratio design sumptuously using a transistor. And the straight DC circuitry to which phone amplifier is direct connected to the power stage is taken in, and the quality of the disk play is raised. Furthermore, highly precise MC head amplifier and a subsonic-speed circuitry are built in phone amplifier. A subsonic speed is used only to an equalizer and is attaining simple-ization of other functions. A tone control carries out "the ±8dB variable" of "100Hz" which is a right-and-left standalone version which a fine balance can adjust, and the "10kHz." And adoption of a highly precise volume has realized the entire flat response at the middle point of a thumb. The peek power meter of a window is suddenly equipped in the center of the front panel. It differs from the bar window, and since light emitting diode displays power on a point in a pure Class-A and AB class, clear moreover, the Direct reading of the exact output can be carried out. Moreover, under meter, the dubbing circuitry in which a mutual sound recording is possible, and two speakers hear it from the deck to the deck, it compares, and abundant functionalities which can perform a simultaneous play, such as a speaker multiple contact switch, are incorporated.
