Default Amplifier Transistor Replacement Help

Hello all!

First of all I am obviously new to the forum and despite looking, please forgive me if I am posting in the wrong section or have missed where this is previously answered.

Now, I am looking to replace a transistor in my Rockford-Fosgate 1200W dual-channel, because I overheated the amp and burned it (my fault, I admit). Now, I cant get any identification off of it due to damage, but I do have an identical amp that, if possible, I could steal the transistor from.

My question is two fold. First, from my reading here I have noticed the extreme sensitivity with changing these, and that leads me to ask if you all think this could be safe since they're identical amps and it would be from the exact same spot as the burned one. Second is simply how to do it, since I cant seem to get the bad one dismounted.

I am good with electronics, although most of my experience is with automotive and household, apart from things like xbox modification. Thus I am new to this area of solid-state and appreciate any input!

Sorry for the long post and thanks for any help!

Working with unknown parts is a sure-fire recipe for disaster where you wind up binning 2 instead of just one amp. Sure, you could be fortunate and do the transplant right first time, but are all the parts like this one unidentified? Can you post the part I.D., assuming it is an industry p/n. (Google it and check first) Perhaps the brand should tell us, but are these not automotive amplifiers?

The auto forum might be more directly helpful with knowledge of particular models and general substitutions that may work. However, if you are having difficulty removing the part, you will need specific details anyway.

PCB soldering techniques are not that difficult but removing solder first with special fluxed braid or a special sucking pump is the only way to make parts removal safe and quick. See your local parts store or wade through massive catalogues on-line, but these are very common electronics accessories.

Well, that's the thing. There's like 18 transistors, and like 5 different sets of markings, so I dont know what set this particular one belongs to. The difficulty is that it seems to be epoxied to a metal plate type thing that dissipates heat to the outer case, as the case acts as a giant heat sink.It is that epoxy/glue that is holding me back

I can post pictures if that would help at all

I actually have a good solder iron and tip set, along with a solder pump and such from my xbox dabbles.
