求助:前級的機殼有訊號傳入返前級!!

請問各位!!!

最近發現前級的機殼有訊號傳入返前級, 每當輕輕拷機殼一o下,喇叭都會聽到放大了的噹噹聲!!
有什麼問題發生呢?? 會不會有大問題出現??
希望大家比點意見呢!!

Thanks!!

I think some of the component is loosen. I have that problem before on the output capacity, once I tighten up then it is ok. Hope this help.

i has the same idea as accphoto, possibility of component loose is high.

Many Thanks for Accphoto & WINDWSS,
Let me try to open the cover to check the parts.
Hope i can fix the problem!!

Thanks so much!!  :

可能是前級那些膽安裝得太實，當拷打機箱時所產生的震蕩，在膽座下些功夫吧！

可能也是喔, 我問過一些老師夫,他也說應該是個膽接收了震盪的聲音再放大造成!!
這是近代膽機(可能是平價)的通病吧!!! 無得攪!!!

但是如何可以在膽座中做手腳呢??

Many Thanks!!
