Features

Accuphase's first integrated amplifier developed taking advantage of the technical achievements of P-300 and C-200.

A parallel push-pull circuit using a large power transistor is adopted as an output stage.
Furthermore, the bias current of each stage is examined. This reduces the distortion at the time of small output and improves the sound quality at small output.

In the power supply section, a large power transformer and two 20,000uF filter capacitors are carried.
In E-202, all amplification stages except for the output stage are made constant voltage. As a result, stable operation is realized by suppressing fluctuations in power supply voltage.

n the equalizer amplifier section, a direct-coupled three-stage circuit of constant current load type differential amplification is adopted. This realizes excellent linearity. Furthermore, the allowable input voltage is raised by ± 2 power supply system.
In addition, a low enhancement switch mounted on the C - 200 and a subsonic dedicated filter for the disc are provided.
Low enhancement can correct subtle presence that can not be corrected by tone control.
The disc subsonic filter prevents feedback due to motor vibration and arm resonance.
The DISC 1 input has an attenuator that can be changed by 6 dB and an impedance changeover switch.

In the tone control circuit, a step switching circuit with a fixed turnover frequency is adopted.
In addition, independent switches are provided so that comparison with flat characteristics and tone ON-OFF can be performed.

You can switch the damping factor of the amplifier.
This was considered to match the speaker designed in the tube amp era, it is possible to switch to 3 stages.

Speaker protection circuit is carried. If the cord shorts after the output terminal or an abnormality occurs inside the E-202, it will be shut off by the relay and protect the speaker.
Also, like the P-300, an impedance detection circuit is built in. In this circuit, when the speaker terminal is short-circuited before the switch is turned on, the relay does not come in.

The power meter is carried.
This power meter has separate left and right channels. In addition, it is possible to switch the meter range. This allows monitoring even at small output.

A walnut cabinet was sold as an option.
