 92331904006681560 McIntosh MC2105 Stereo Power Amplifier

Here is a McIntosh MC2105 Stereo Power Amplifier. This unit is serial number AH2022. It has the following specifications. MC 2105 ELECTRICAL SPECIFICATIONS: POWER OUTPUT: 210 watts RMS continuous power stereo, 105 watts per channel. Both channels operating into 4 ohms, 8 ohms or 16 ohm loads. HARMONIC DISTORTION: Less than 0.25% at rated power output from 20 Hz to 20kHz. Both channels operating. Distortion typically measures less than 0.1%. Distortion decreases as output power is reduced. INTERMODULATION DISTORTION: Less than 0.25% for any combinations of frequencies between 20Hz and 20kHz at 210-peak watts output per channel or at any level less than 210 peak watts per channel. Both channels operating. FREQUENCY RANGE: At rated output both channels operating +/-0, .25db 20Hz through 20kHz. OUTPUT IMPEDANCE: 4 ohms, 8 ohm, and 16 ohm. Full rated power output is provided at each output tap. The 8 ohms output will provide 25 volts RMS for constant voltage multiple speaker distribution lines. OUTPUT DAMPING FACTOR: Greater than 18 at 4 ohms. Greater than 13 at 8 ohms. Greater than 10 at 16 ohms. INPUT SENSITIVITY AND IMPEDANCE: 0.5 volts will produce rated power output; a gain control is provided for each channel allowing independent adjustment of amplification in each channel. Input impedance is 200,000 ohms. HUM AND NOISE: Greater than 90dB below rated output. OUTPUT POWER MONITOR METER: Meter is calibrated to read 0dB when amplifier produces rated output. Meter range switch is provided to increase meter sensitivity by 10dB or 20dB. HEADPHONE OUTPUT: Designed for low impedance headphones. CONTROLS: Power on-off switch, speaker on-off switch, left gain, right gain, and meter range switch. SPECIAL FEATURES: The amplifier is completely stable when connected to any loudspeaker system or reactive loads. The MC 2105 has special circuitry to prevent damage by inadvertent or intentional short circuit or open circuit of the output loads, or by any amount of the output impedance mismatch. Thermal cutouts are mounted on the output transistor heat sinks to provide protection in the event of inadequate ventilation. SEMICONDUCTIOR COMPLEMENT: 34 silicon transistors. 18 silicon rectifiers and diodes. POWER REQUIREMENTS: 117 volts AC 50-60 cycles, 90 watts, at zero signal output, 430 watts at rated output. MC 2105 MECHANICAL SPECIFICATIONS: SIZE: Front panel, 16 ?" wide by 7 1/8" high; chassis 14 7/8" wide by 6 9/16" high by 14 ?" deep, including connectors. Clearance in front of mounting panel including knobs, 1 ?". FINISH: Front panel is anodized gold and black. CHASSIS: Chrome and black. This particular piece is in excellent condition both cosmetically and operationally except there is some distress on the black surface behind the glass as pictured. The unit has all lettering intact. For the sake of flexibility, the cabinet is being sold separately. Please see my other auctions for this.
