Ok Mac guys....I need some help. I just built a new family room on my house. Along with it, I added a few Mac pieces for my "home theatre" which included 2 MC 7108's. One for TV use and one for the satellite speakers throughout the house and on the patio. So I pick up both amps and sure enough the bulbs are bad. So I order the bulbs through McIntosh and install them myself. They all work but the faceplate on one of the amps is a lighter green than the other amp. It's almost a dark yellow as opposed to the trademark McIntosh green. I'm stumped. Any ideas? Thanks.
