[QUOTE="hispls, post: 8069935, member: 614752"] The big problem you'll find, in addition to the fact that most companies will be very tight with releasing schematics (and some companies are long gone), is that many of them scratch off part numbers on their IC chips so that people don't know what they use. Really silly at this point since pretty much every far east amp is basically the same thing (according to reliable sources). Still though IMO as far as the common stuff if you can fix one you should be able to fix them all. Keep in mind, many of the ones that are commonly available blown are blown because they're terrible designs and no matter what you do, you won't be able to change that, so you're opening up some risk on yourself, bringing a piece of crap back to OEM specs still makes it a piece of crap that will probably fail again (making you look incompetent). The reputable amp shops stay away from certain things for a reason. Also, there's really good money to be made in amp repair if you can get good at it and know how to treat customers right. Good luck to you. [/QUOTE]
