Audio Research CA50 Stereo KT88/6550 Tube Integrated Amplifier with Original Remote Its 2x45 Watts RMS with KT88/6550 tubes in output. Net weight is about 50 lbs. The amp works fine in both channels. However there is low level hum.I think the caps need replacement. Physical condition is very good for the age. Overall, this is an excellent vintage ARC product. Sale includes the amp, remote; no box or manual. Please examine the photos carefully, for they are part of item description.
