嘉士伯VC15音箱故障问题
各位大神，小弟的嘉士伯VC15使用后待机开关关闭但电源开关未关，一晚上后发现机箱电源插口处的保险丝熔断了，换了二个新的一装上去就熔断，我的是英式230v的电源，求助可能会是哪里原因啊（短路啥的），谢谢！ Replace tube for your ampsYou know a tube had gone bad when:
以下情况发生时，你必须换管子
1) Your amp develops and uncontrollable high pitch squealing feedback. (A tube has gone micro phonic. a micro phonic tube can happen any time, but old age, or a sudden jar while still warm will be the most common causes)
音箱发出不可控制的啸叫回馈时。管子发光浑浊时。管子浑浊的情况比较多见，老化，或者猛然的震动都可能是其原因，但仍然会发热。
2) Output power loss.
输出功率减少或有损失。
3) Loss of gain in a high gain amp. (can also be caused by a bad cable occasionally. check that first)
高失真音色失真效果减弱。太差的连接线有时也造成此情况。
4) Tube color changes from warm orange to a blue, pr purple cast. Even if it still works fine, it's on it's last legs. Change it.
电子管颜色由暖色调的橘色光变成蓝色，？？紫色的光？？即使能正常工作，其实已经坏了，换。
5) Amp used at the same settings is suddenly noisy with hiss, or hum.
相同设置下，有了噪音或hum hum声。
6) Oscillating tonal changes.
声音变调。
7) Amp suddenly won't stay powered up, and you keep blowing the fuse.
箱头电源打开但总是不亮，保险丝老是烧掉
8) When turned off, the tube is not clear but has a slight whitish cast.
当关掉箱头后，电子管看起来不透明，里面有点发白的东西 7) Amp suddenly won't stay powered up, and you keep blowing the fuse.
箱头电源打开但总是不亮，保险丝老是烧掉？
