虽然各种各样的音响集成功率放大电路相续问世,但由于价格较高,不少爱好者还力所不及,本文介绍的全晶体管立体声功率放大器,既可以降低成本,还能使初学制作者真正领会到音频功率放大器的一些基本原理,该放大器用6 V电源供电,它可在8 Ω负载上获得0.5W最大输出功率,如果负载阻抗为4 Ω,则最大输出功率为0.8 W,虽然每路声道的输出功率不算大,但它具有较高的传真度,失真极小,总谐波失真小于0.5%,若能与性能优良的音箱连接,该音量是
Although a variety of audio integrated power amplifier circuit come out in succession, but due to higher prices, many enthusiasts are also powerless, this article describes the all-transistor stereo power amplifier, both to reduce costs, but also beginners Truly appreciate some of the fundamentals of audio power amplifiers that operate on a 6 V supply that can achieve a maximum output power of 0.5 W at 8 Ω and a maximum output power of 0.8 W at a load impedance of 4 Ω, Road channel output power is not large, but it has a high degree of fidelity, minimal distortion, total harmonic distortion of less than 0.5%, if you can connect with good performance speakers, the volume is
