I need some advice guys.
I have an American Audio GX-300 Power Amp i use in my studio. Bought it used off of EBay. Been working like a charm for almost a year. One day while tunning up a guitar the amp shut off. Found it blew a fuse. I replaced the fuse switched it back on and it blew again.
Finially had to take it in . I was told that an Output had gone. Cost me 140 bucks Canadian to replare it.
I get it back a week later. Take it home, plug it in. And bang the fuse blows again right away. I return the amp to the repair shop. 2 weeks later i get it back. They told me the Output the guy replaced was fautly and get this he wanted more money to fix what was suppose to be fixed properly in the first place.
Any i get the amp back, worked fine for a week. Then 1 day i turn it on and it pops the fuse again. I replaced the fuse and it worked fine. A week later turn it on again and it popped the fuse again.
I'm not taking it back the the these guys again. I'de rather try and diagnose the problem myself and fix it.
Any ideas to where and what i should be looking for and were to start looking for the problem?
I've been doing alot of research and am comfortable with electronics to try and narrow down the fault and fix it.
Any help would be greatly appreciated. If you need any more ifo i can provide it. I also have the schematics for the amp aswell. That was a bonus courtasy of American Audio Inc.
