McIntosh MC275 Tube Stereo Power Amplifier
With Original Manual

McIntosh Laboratory's MC275 is as classic as they come. Introduced in 1961 as the "powerhouse" of that era's newfangled stereo tube amps (two 75W amplifiers in one chassis!), the MC275 retained its position as the amplifier to own until 1970, when it fell prey to the widespread wisdom that transistors were king and tubes were dead, and the model was discontinued. The unit offered here is in immaculate condition and has been fully serviced and operates flawlessly. 

Description: Two-channel, tubed stereo (switchable to parallel mono operation) power amplifier. Tube complement: four KT88, three 12AX7A, four 12AT7. Inputs: 1 pair single-ended (RCA), 1 pair balanced (XLR). Loudspeaker outputs: separate gold-plated, 5-way binding posts for 4, 8, and 16 ohms. Preamp output: 1 pair single-ended (RCA). Inputs: 1 pair balanced (XLR), 1 pair single-ended (RCA). Output power: 75Wpc (18.8dBW) into 4, 8, or 16 ohms (stereo), 150W into (21.8dBW) 2, 4, or 8 ohms (mono). Frequency response: 20Hz–20kHz, +0/–0.5dB; 10Hz–70kHz, +0/–3dB. Signal/noise ratio: 100dB, A-weighted (no reference level given). THD: 0.05% at any power level from 250mW to rated power output. Input sensitivity: 1.2V unbalanced, 2.5V balanced. Input impedance: 90k ohms unbalanced, 180k ohms balanced. Damping factor: >14 (wideband). Power consumption: 170W (idle), 360W (full power).
