Page 3: General Description
The dramatic difference in the quality of The MC275 has on one chassis two 75 music reproduction when you listen through watt power amplifiers. In addition to its use Mclntosh instruments is directly due to low as a stereo amplifier, the flexibility of the distortion performance. -
Page 4: Technical Description
The Mclntosh circuit in reality perfects push-pull high efficiency output circuits. The MC275 uses an advanced design of the Mclntosh output transformer. The new Fig. 2—Representation of Mclntosh output circuit. - Page 5 (less power amplifier. than 0.5 ohms). Current is thus limited when Good voltage regulation in the power the MC275 is first turned on but is not supply permits overloads without overshoot limited as the unit warms.

AC POWER LINE OUTPUT-MONOPHONIC The MC275 operates on 120 volt, 50 to 60 To feed a 25 volt line, connect one side to cycle power. The amplifier will be turned on the screw marked COM on the LEFT barrier and off if its power cord is plugged in one strip. - Page 12 LABORATORY INC. 2 CHAMBERS STREET, BINGHAMTON, NY 13903-2699 Made in U.S.A.
