Can I fix a fried amp? (by 2 users)

posted by Tido on Jun 06, 2006


I was hooking up a compaciter and didnt realize the compaciter had a charge stored in it. When tring to hook up to my amp, it touched the chassis of my amp and the amp has ceased to work. Checked all four external fuses hoping it just blew one of them, but they are all fine. Is there anyway I can fix it inexpensively because I have no warranty on the amp.

I have an explode amp that recently stopped giving any output,i was not using a fuse from the battery but the fuses on the outside of the amp are still intact and the power light still turns on,is there any way the amp could blow without the fuses blowing?

Hi, how good are you with electronics? Are you able to open up the amp and see any obvious problems? I suggest that if your not very good with electronic circuits, get a professional to have a look at it, as if you damage it more by trying to fix it your self, it will probably cost you more to fix it. It may be as simple as an earth track been burnt, but even that in most cases will force you to completely disassemble the amp to find the problem. It may also be the diode right next to the power supply terminals that may be damaged and in some cases that can cause problems. Let me know if you open the amp, if possible post some pics and will see if there is something obvious that stands out.


Cheers

Many amps have a zenor diode in them that will protect the amp in the event of a short this diode is cheap and easy to replace. take the amp apart and look between the positive and neg rails on the board it will be there any one that sells them can test them if yiur multimeter does not have a diode check feature.
