Marantz PM-6 150,000yen

The Integrated Amplifier which adopted the design of separate amplifier SC-6 and SM-6.

Pure Class-A 30W+30W by the stream composition of whole page perfect push pull DC. Freshness is high and switching distortion etc. is the power which is not generated theoretically.
moreover, even a switchpoint comes out and a modification is also possible to AB class 120 W/ch. Since the difference of the sound by change is contracted, the high speed high fT transistor which fully attained wide band-ization for cut-off frequency with 90MHz is adopted as the power stage. Switching distortion called weak point of AB class was suppressed to the relative minimum, and it is delicate and, and yet, is finished in powerful AB class amplifier.

The control amplifier part also serves as a Low-TIM design with the power amplifier part, and a nakedness property is improved by the material selected carefully and the proficient circuitry. The amount of NF was reduced and the distortion on Hearing impression was banished.

A power-source part is filled up with the newly developed 22,000-micro F super audio capacitor and a special resin, and the compact transformer which took heat-resistant measures is adopted as it.
Furthermore, the heat pipe with high effectiveness was carried in the heat-dissipation organization, and the high exothermic at the time of a pure Class-A operation is cooled in it.

In order to raise the quality of a disk play, the straight DC switchpoint to which phone amplifier is direct connected to the power stage is equipped.
For this reason, the transistor which also attains to channel 13 stone of one side is used for the Low-noise-izing of each block, a raise in an S/N ratio, and MC head amplifier handling a detailed signal, and it polishes even on the level which is fully worthy also as a single article.
Moreover, a phone input switchpoint is equipped with the cartridge loading selector of 27kohm, 47kohm, and 100kohm, and any cartridges are supported.

The design of a right-and-left independency is adopted as a tone control circuit. Moreover, 2 point variable type is adopted as a loudness circuitry, and two kinds, +8dB and +4dB, can be chosen as it in 100Hz.

Speaker change-over-switch loading in which a simultaneous play and a change are possible.

Subsonic-Filter adoption which cuts unnecessary super-low-pass one.

Mutual dubbing circuitry loading by the two decks.
