You should call Outlaw but they didn't void my warranty on my 7500 after I opened it up to replace the controller card at home. They sent me the part with some info and I replaced it. There was nothing wrong with the amp. I thought the way it started up was odd but turns out it was normal. You will have to pull the amp no matter what unless it suddenly heals itself and even then the melted plastic smell would keep me awake at night as long as it was plugged in. Could it have gotten fried by lightning or some other voltage transient? If so homeowners insurance should cover it. Any chance you popped a circuit breaker or GFI on one of the circuits it is plugged into? Listening in stereo should not even come close to challenging the power supplies but you never know for sure.
