输出功率太低，请求更换功放管。
The output power is too low. Require to replace power tubes.
场效应功放管在全固态发射机的射频功放中应用得越来越广泛。
The power FETs are more and more widely used in radio-frequency power amplification in all-solid state transmitter.
本文作者通过自己在工作中的摸索和积累，总结出了一套更换末级场效应功放管的方法和操作步骤，以供同行参考。
Based on his work experience, the author puts forward a method and operation procedure for replacing final power FETs for the colleagues' reference.
由于末级场效应功放管价格昂贵，当管子损坏需要更换时，对防静电的要求很高，一旦操作不当就会损坏管子，造成损失。
As final power FETs are very expensive, the antistatic requirement is quite high in replacing damaged FETs. A misoperation would destroy FETs and cause loss.
