Commentary
An AM/FM stereo receiver that combines an AM/FM tuner and amplifier.
The design is unified with KR 4200.
It is equipped with a microphone mixing circuit that can be mixed with records, AUX, AM, FM, etc. By pulling off the mixing volume, it becomes MIC-only, and the microphone level changes only by the microphone volume.
Equipped with two types of speaker terminals.
