Description :
The McIntosh MC2205 Stereo power amplifier carrying a power meter. It hits the power-meter loading model of MC2200. Distortion is removed by using the monolithic transistor differential amplifier with few noises for the input side of a power amplifier circuitry. An input signal and a feedback signal are supplied to this differential amplifier. The circuitry of the following stage is a voltage amplifying circuit of a Class-A operation, and a driver circuitry and an output circuit adopt a complimentary scheme, carry out the operation near a Class-A, and are reducing crossover distortion. To the transition of a temperature, this circuitry is designed so that a moderate bias may always start. A power transistor is AB class operation and, as for the bias current, the safeness is maintained by the thermistor.
