¥ 80,000 (around 1972)
Commentary
An ES series power amplifier that pursues not only power supremacy but also ultra-low distortion.
In addition to the output coupling capacitor, the coupling capacitor between each stage is removed, and a direct coupling method using a pair of transistors with excellent characteristics is adopted.
Uses a protection circuit that detects the output current and controls the current of the output transistor.
Equipped with a power limiter switch that limits the maximum output to 1/2 or 1/4.
Equipped with two inputs and two outputs, each of which can be switched with a switch.
Equipped with a knob for adjusting the input level.
It is equipped with a special circuit to protect the speaker during abnormal operation.
