I've had this for about a year and have used it quite a bit, but never very loud. It started acting up the other day, after I powered it on, no speaker relay click, then it turned itself off. After a couple times it would kick on and stay on, but it took a while; what I've heard called a "lazy" relay. Today I couldn't get it to come on at all. The power cord got impaled by one of the spikes on my stand as I was moving the stand, but looked to only be superficial damage. I spliced in a new power cord hoping the fix would be that simple, but no dice. Is there any chance that it's the speaker relay itself? I don't see anything melted or burned inside, and like I said, when the relay clicked before it worked fine.
