As you can see by pictures this is a 1960's Fisher KX-200 Master Control Amplifier rated at 35 watts RMS per channel. Has sat dormant many years, I brought up slowly on variac and unit did pass signal. Tubes on left side as your facing unit were wanting to go thermal so I shut off. The right side output is weak but there. Will definitely need service repair updating and therefore and as is sale. Tubes are all original Fisher I believe.
