本文介绍的6GW8推挽功率放大器主要采用ISO公司的小型输出变压器,该变压器体积为56×50×81mm~3,制成后的功放十分精巧美观。全机仅使用一种型号的真空管6GW8。电路原理如图1所示。1.6GW8的特性6GW8是美国型号,欧洲型号为ECL86,它与14GW8/PCL86除灯丝电压不同外,其它技术参数均相同。6GW8的相似型号为6BM8。此类胆管在音频放大器输出级中被广泛采用。6GW8为旁热式阴极三极—五极复合管。三极管部分用于电压放大,五极管部分用于功率放大。三极管部分在
This article describes the 6GW8 push-pull power amplifier mainly uses ISO’s small output transformer, the transformer volume of 56 × 50 × 81mm ~ 3, made of the amplifier is very beautiful. The whole machine uses only one type of vacuum tube 6GW8. Circuit shown in Figure 1. 1.6GW8 features 6GW8 is the United States model, the European model ECL86, 14GW8 / PCL86 with it except the filament voltage is different, the other technical parameters are the same. A similar model for 6GW8 is 6BM8. Such bile ducts are widely used in audio amplifier output stages. 6GW8 for the next hot cathode three-pole - five-pole composite pipe. The transistor part is used for voltage amplification, and the pentode part is used for power amplification. Transistor part in
