Audio Research CL-60 Classic 60, available in Silver or Black

Here is your chance to own a classic tube amplifier at a reasonable price.

The CL-60 delivers 60W using 8 x 6550 output tubes (it actually measured closer to 65W before clipping) while maintaining the traditional warm and precise Audio Research signature sound.

This is a well-built American made unit (not a recent Chinese attempt at HiFi) weighing in at 63 lbs. It is made from the highest quality components available at the time and was hand assembled with care and attention in their Minneapolis factory.

Condition is superb for an amplifier of this age. The paint is very clear with no noticeable scratches or dents. The faceplates are also very clean, specially the black one. There is no rust or signs of exposure to moisture anywhere.

The unit was bench tested carefully and it passed with flying colors. All tubes were tested and all capacitors were inspected and tested for leakage. It was driven to its full power rating while monitoring distortion without hiccups. It then was moved to our listening room where it powered our vintage B&W Matrix 801’s with authority and precision and made a really nice and pleasant combination.

This classic tube amp is available in the color of your choice as I have both silver and black faceplates available.

Included is the amplifier with a printed instruction manual.

Some Tech Specs:

Description: Stereo, hybrid tube/FET power amplifier. Tube complement: four matched pairs of low-gas 6550s, four 6FQ7/6CG7s. Maximum power output: at least 60W into 16 ohms (20.8dBW), 15Hz-20kHz, with less than 1% THD; typically 62W at 1kHz with 120V AC line. Power bandwidth (-3dB): 12Hz-40kHz. Input sensitivity: 550mV RMS for rated output. Input impedance: 100k ohms. Output regulation: approximately 0.3dB, 16 ohms to open circuit (equivalent to an output impedance of 0.56 ohms—damping factor quoted as approximately 30). Negative feedback: 20dB. Slew rate: 20V/µs. Risetime: 2µs. Hum and noise: less than 2mV RMS—84dB below rated output (20kHz bandwidth, unweighted, input shorted). Power supply energy storage: approximately 280 joules. Power requirements: 500W at rated output, 700W maximum, 370W at idle.

Dimensions: 19" (480mm) W by 7" (180mm) H by 15.75" (400mm) D, handles add 1 5/8" (41mm) to depth. Weight: 63 lbs (28.64kg).
