All parts operate normally. About the Product Marantz PM-5 List Price 110,000 Yen This is a pre-main amplifier that can switch between pure Class-A and Class-AB. In addition to pure Class-A 20W/ch, it can switch between Class-A and Class-AB 80W/ch. Moreover, in order to raise the quality of Class-A to the level of Class-A, the high-frequency cutoff frequency is set as high as 90MHz. This eliminates switching distortion, a drawback of Class-A amplifiers, to the utmost limit. In the PM-5, all stages are fully push-pull DC amplifiers in order to eliminate TIM distortion from every corner of the amplifier, improving the bare characteristics. Transient intermodulation distortion and static characteristics are improved without applying a large amount of NFB. A newly developed heat pipe system is used in the heat dissipation mechanism to enhance stable operation of the power transistors. The heat is directed out of the circuit and cooled by a radiator, allowing the transistors to be placed in ideal positions, simplifying the circuit and reducing distortion. In addition, the power supply section is compact with large capacitors developed for audio applications and filled with a special resin to provide heat resistance, The phono amplifier block uses transistors in particular. The phono amplifier block is a low distortion, high signal-to-noise ratio design that makes lavish use of transistors. A straight DC circuit that directly connects the phono amplifier to the power stage is used to enhance the quality of disc playback. In addition, the phono amplifier incorporates a high-precision MC head amp and subsonic circuit. The subsonic circuit is used only for the equalizer to simplify other functions. The tone controls are left and right independent for fine balance adjustment, with ±8dB variable at 100Hz and 10kHz. Moreover, the use of high-precision volume control knobs ensures a completely flat response at the knob's midpoint. It also features a loudness control to compensate for low and high frequencies. A peak power meter with a dot display is provided in the center of the front panel. Unlike a bar display, the LEDs indicate power in points for both pure Class-A and Class-AB, allowing clear and accurate direct reading of power output. The dubbing circuitry under the meter allows mutual recording from one deck to another, and the power meter is also equipped with a built-in speaker output filter, A speaker selector switch allows you to listen to two speakers and playback two speakers at the same time.
