Pioneer Stereo Receiver Amplifier ES-1 Wood box specification. This is a used item. There are no noticeable stains or scratches, but please refrain from purchasing if you are sensitive to such things. The audio output as an amplifier has been confirmed. As for the radio tuner, I have not connected an antenna cable, so there is a response, but I have not been able to confirm clear audio. The switches etc. seem to be working normally.
