國產合併AMP改機求救

Simple check the following step by step

1) did you unplug some cable ? i.e. Input source
2) did you destroy the solder pad when disassemble the old capacitor ?
3) Any dry soldering?
4) What kind of soldering gun you are using? May be your soldering gun have higher ESD to destroy the 2'nd stage amp.

請問是否u 數過大？ (底板上是寫住10u 100v)[/quote]
