This Pioneer QL-600A Quadralizer Amplifier is a vintage piece of electronics that is in wonderful condition and has been tested for basic function. I hooked up a turntable to the aux for rear speakers and it did drive a pair of speakers well and powerful. The level indicators worked for the rear speakers as well. I did not attempt to hook up anything for the quad function. All switches seem to work and all knobs are solid and in nice condition. I did not open up the case and clean anything inside. It comes with a beautiful wood case that adds to its vintage charm. This amplifier is perfect for music lovers who appreciate vintage audio equipment. Its quadralizer function provides a unique audio experience that enhances the sound quality of any audio source. The Pioneer QL-600A is a rare find that will be a great addition to any collection.Fantastic piece, as with any vintage guaranteed working on arrival, after verification it works, thats as far as it goes as a warranty.
