SEPP 电路常见于日本电子报刊,SEPP 实际是指串联供电的单端推挽功放。为了不用输出变压器组成电子管 OTL 功放,近年来各大厂家采用低内阻大功率三极电子管组成直流供电串联、交流信号并联的方式组成功率放大器,这种放大器的特点是负载阻抗仅为普通推挽功放的四分之一,再加上采用特殊的低内阻三极管很容易使负载阻抗达到32Ω以下,从而可以直驳8Ω或16Ω的扬声器。目前由6C33C、6H5P 等组成的此类功放性能优良,国内厂家也普遍采用。在日本 PP 被用作推挽电路的简称。实际上单端推挽胆功放是1966
SEPP circuit common in Japan’s electronic newspapers, SEPP actually refers to the single-ended series push-pull power amplifier. In order to not have the output transformer tube OTL amplifier, in recent years, the major manufacturers of low-resistance high-power three-pole tube composed of DC power supply in series, the exchange of signals in parallel to form a power amplifier, this amplifier features a load impedance of only ordinary push-pull A quarter of the power amplifier, coupled with a special low-resistance triode, easily allows the load impedance to 32Ω or less, which can be directly barbed 8Ω or 16Ω speakers. At present, 6C33C, 6H5P composed of such power amplifier performance, domestic manufacturers are also widely used. PP is used as a push-pull circuit in Japan for short. In fact single-ended push-bile amplifier is 1966
