I bought an Adcom GFA-555II amp in an online auction from a seller with a perfect feedback history. His auction said the amp works flawlessly. I received it and it doesn't work. Given the seller's history, I trust that it worked last time he tried it.
But it doesn't work, now. The red light doesn't come on. No sound is produced. After turning off the power switch, there's a bit of a sputter played through the speakers. This seems somewhat normal. My Adcom GFA-535 used to do that and it worked fine the whole time I had it. The GFA-545II in my present system does not do this, though. There are 5 fuses accessible from the back and they all check out good. The amp was well-packed and the box did not suffer any damage in transit.
Any ideas about what may be the problem?
