I did recently got a display model of the Sherwood RX-4109 receiver and I was wondering that since it was used to power the speakers for the store as background music but do you think it still like new? They didn't have the volume up loud so it was very low and they started to use it a year and a half agao. But I got $15 off because it was a demo and it was in use. I just wonder if the amp got any stress from being in use for a long time or should it be perfectly fine? I got this receiver at Radio Shack.

So far everything works and it powers up but just wanted to know that do you think it had any stress because it was on alot. At least it was never turned up since they can't have it too loud.
