Description
Very rare, very powerful unit. This would be considered a 7.5/8 on condition. As pictured, There’s some superficial corrosion stains on the top of the unit and sides. The face and knobs are in very good condition. The main volume know has a few superficial scratches. The unit was tested and sounds fantastic. Only thing I could note was the red light next to the tuner on the selector knob did not light up. All the others did. Please ask any questions. This unit is heavy (60lbs) so will not be cheap to ship. The Pioneer A27 is one of the highest quality integrated amplifiers Pioneer has brought to the market! Up to 30W, the A 27 works in pure Class A mode.
