Stereo power amplifier, which challenged all possible limitations regarding sound quality. Design developed, used parts, circuit configuration, manual work - everything was aimed at improving performance. Power transistor with four parallel connections (eight per channel). A push-pull A-class scheme allows you to transmit clear sound even with a weak incoming signal. The power supply operates stably regardless of the power and stability of the low-frequency and high-frequency ranges, and has excellent temperature stability. The power meter directly reads a wide range without any sensitivity switching.
The printed circuit board is made of epoxy resin, the elements are selected carefully, with high reliability. Elements in the design of the transformer, allowed to minimize the leakage of magnetic flux. The amplifier is equipped with a cooling system of two fans operating at low speeds at low voltages in order to minimize the resulting noise. Pioneer Exclusive C3 is also equipped with an effective overheat protection system in addition to the cooling system. With full quality control, Pioneer guarantees high performance and stable operation of the power amplifier. The cost in 1974 is 350,000 ¥.
