Hi all, I picked up a viper 1100.5 5ch amp,its pretty old but is very clean. Put some power to it and it goes into protect mode and stays that way. So I opened it up and can see that somebody had done some work on it in the past. It seems some devices were replaced and I wanted to make sure that they used the right parts or at least equivalent ones. So my question is would anyone have a schematic or maybe some pics of the board that I could compare with. Thanks in advance

Post photos that allow the face of each heatsink mounted component to be clearly read and I'll compare them to the photos I have.
That looks right.
The vertical boards with the potentiometers develop bad connections. You need to add new solder, desolder and resolder. Simply adding new solder will be less reliable.

Ok I'll give it a shot,also I wanted to mention that when I opened up the amp I found a transistor that one of its legs burnt off and blew a hole through the transistor,it was labeled C3918GR,I've since replaced it and repaired the burnt trace it was attached to. In a different location I found a ceramic capacitor that was also cooked. One leg of the cap was attached to the same trace as the burnt leg of the transistor. I replaced the cap and put power to the amp,still in protect. That's as far as I got so far,but I'm sure that I'll need help on this one haha. I'll post some more pics asap
Here are the pics,I forgot to mention that I also found a 10uf 200v non polarized cap that was bulged,hard to see in the pic but it is definitely bulged and not sure what to replace it with as I cant find anything similar on digikey. The 4th pic is of the area I found the burnt transistor,you can see the red wire I used the repair the trace going to the transistor I replaced it with.
