Pioneer A-8800X
59,800yen(around the 1979 time)

Description

The stereo Integrated Amplifier which adopted the direct power supply.

The direct power supply scheme has composition which included the power source for exclusive use in each of the small signal circuit board (an equalizer amplifier, flat amplifier) and the Taishin number circuit board (power amplifier). Therefore, each power source is directly linked with each circuitry, there is no leading about of a code, and large low-impedance-ization is enabled. Furthermore, since the cross interferencee of an amplifier inter-unit can also be prevented, the improvement in a tone quality has been obtained.

In addition to the large-sized transformer, in two right and left, the power-source part arranges the power source capacitor to each parallel, and is stopping the impedance of the capacitor low.

Newly developed Super Linear RET (Ring Emitter Transistor) is adopted as A-8800X.
This was developed with the power amplifier M-25, is the ensemble transistor excellent in the switching characteristic of a high region used also for the magni-wide amplifier A-0012, and has improved the linearity at the time of an effective output sharply.
Furthermore, newly developed T type Skype fin is adopted as a radiator, and the heat-dissipation effect is heightened 50% or more.

MC position which MC cartridge can connect direct is carried, and man month/MC can be chosen by switchpoint switching of the front panel.

The cascode current mirror interconnection and the FET difference input circuitry are used for the Phono input unit.
Moreover, the flat amplifier part has adopted the circuitry of the 2 steps of differentials stream composition by newly developed can type low-noise dual FET.

DC amplifier stream composition which removed the capacitor from the input circuit and NF circuitry is used for a flat amplifier part and a power amplifier part, and while being based on a capacitor, they are suppressing the - low-pass phase shift, the failure of a dumping, and the occurrence of transitional cross modulation distortion.

Switchpoints, such as a function change, adopted the soft push type in which one-touch control is possible, and the tone control, the cartridge, etc. have adopted rotary system as what needs to check a transition of a tone quality continuously.

Since the performance of man-month cartridge is demonstrated more, load resistance and load capacity can choose three steps independently, respectively.

The tone ON-OFF switchpoint is carried.

2 tapes monitor and the tapes duplicate switchpoint are carried.
Moreover, the loudness contour and the Subsonic Filter are carried.

There was a wood cabinet as an option.
