Up for sale is a Acoustic Research AR A-06 Integrated amplifier. It is very good condition for it’s age. It has been listed as parts as it is only partly tested as I don’t have the means to test the outputs however I see no reason why it wouldn’t work as everything I have been able to test works fine. It powers on and all the buttons on the front seems to work great. It comes with rare original box, instructions and packaging. The remote however is missing.
