电子管 Hi-Fi 与 AV 功率放大器的电路简洁,所采用的零部件数量不多,电路中元器件之间的衔接越近越好,所以—般国内外高档的功率放大器采用纯手工搭棚式接法。为了达到高质量的放大效果,故对本功率放大器的零部件布局、装配中的技术要领、调试与校正技巧、输出变压器的估算与绕制等一系列关键性的技术问题作如下简述。 Tube Hi-Fi and AV power amplifier circuit is simple, the use of a small number of components, the circuit components in the convergence between the closer the better, so - at home and abroad high-end power amplifier using pure hand-scaffolding law. In order to achieve high-quality amplification, so the power amplifier components layout, assembly techniques, debugging and correction techniques, output transformer estimation and winding and a series of key technical issues are briefly described below.
