Hello--
I return once again in need of help. My buddy reached out to me about his amp not working (power light not turning on). Quote " i was beating the crap out of it to be honest. But once i smelt a small amount of burning wires I cut all power and turned it on once since them. I had to tap it to come on.". Not sure what "it" is or where...he also sent me a picture of an exploded mosfet, Q707, IRF3205 (? based off the one next to it, not sure that is the correct number).
Now, i know blind part replacement is bad, but, if there are no other visibly damaged parts on the board, would it be a good place to start by replacing the exploded one, and maybe the two on either side of it and seeing if it works?
If that doesnt fix it, I will probably buy Perry's amp repair guide, and go from there.

Don't buy it unless you're serious about studying and learning. Also know that you have to use specific (older Flash-capable) browsers. Very few people are willing to do that. The following is the part of an introduction page that people refuse to read (with only a few exceptions). If you can't get through that, just get what you need here. The tutorial is made for people who want to know amps, not just get answers to repair one amp. That's what the forum is for.

Check the output transistors (FDD3860s?). Is any single FET reading low resistance between any two terminals in any combination (1-2, 1-3, 2-3)?

gotcha, yea, im not really wanting to get into the world of repairing amps, but i dont mind tinkering with them every now and then. And, doesnt really surprise me people cannot read the intro or figure out how to install a font pack. Installing a flash capable browser, however, i can see being an issue.
I need to get my hands on the amp, once I do, I will report back. I assume if its reading low, theres a shorted output transistor and will require further back tracing to find all damaged parts?
It takes all of about 5 minutes to download, install both recommended browsers and the 4 flash files. Downloading them takes about the same amount of time. Start the DL and install as the first one comes in. All are readily available for download on a site that I have for people who want to use Flash (most of my sites). All you'd need is in the framed area at the top of the following page. Testing to see if they're working right (all working smoothly) is done on my old karting page.
