Audio Research Classic 60 Vacuum Tube Power Amplifier in excellent cosmetic condition. The faceplate is in excellent shape with no dings or scratches. The amp chassis and transformers are in very god shape as pictured. Includes the original Audio Research double box shipping cartons and a copy of the owner's manual.
The amplifier works perfect and sounds excellent. It was serviced and retubed at the Audio Research factory a few years ago and has only seen minimal use in recent years. The service cost $1,500 and included replacing all four large filter caps in the power supply and retubing and biasing the unit with new 6550WE power tubes from Audio Research.
The tube compliment of the Classic 60: (4 matched pairs) 6550WE, (4) 6FQ7/6CG7. All power tubes have been biased in matched pairs and test strong. Please note that the plastic guide pin on the bottom of one power tube is missing, but this does not affect its functioning or performance. The Serial Number is # 19346023.
The Audio Research Classic 60 is still held in high regard and received a "Class A" rating and review from Stereophile magazine.
