A friend tried parking his receiver, this is the first time he did it and I never tried so I can't give him any advice. I don't know exactly what method he used but can find out if needed.
But here's 2 pics of it, the left side has a lighter colored area along the top, the rest seems to have come out even. He said he had to lay it on it's side because his pan wasn't deep enough to cover everything if it was placed upright, he didn't say which side was down though.
So can anyone tell what might have happened to cause the difference in color?
