Commentary
A stereo power amplifier in which the main amplifier section of the KA 2600 is independent.
The all-silicon transistor configuration improves the characteristics of the amplifier.
Two types of speakers can be connected.
Equipped with an input sensitivity selector switch, the output from the tuner or tape deck can be directly controlled.
It has a headphone port.
