求救!!! 個合併amp. 突然好細聲, 有得維修嗎??

求救!!!  ops:
我有一個柯頌 V6 i合併amp. 每次開聲後兩分鐘後突然無聲,之後把volume推高先可以聽到好細聲!
p.s. 部amp要熄機起碼幾個鐘先可以再有聲,但兩分鐘後又無聲,, 請問有得維修嗎??

Many Thanks!!

ERIC,

Try the following step.

1. Identify the socket inside the amplifer is OK. If possible, disconnect and plug in once again.

2. Open the PCB (solder side) to check any COLD solder inside, simple is using the iron to fill a new solder.

3. Checking any "hot spot" location, if any capacitor is near it, check that capacitor is OK or not.

If still not OK, should be circuit problem, like damage / leakage inside a diode, transistor.

Hope this help

Hi KK.HO.

Many Thanks for your help!! After i follow your step to check my amp last night. My amp wasn't got any problem at all. So i check all the mechine one by one. And i found that one of the tube in my Tube pre-amp got fail.

Very happy to figure this error out.
