I have a guy that wants to sell me his audioque 2200.1 on the cheap because it is fried, I wanted to know some opinions on whether it is worth the buy/gamble to buy it and see about getting it repaired? Guy says he was playing it at a .5 ohm load and it just cut out and won't come back on. He sent me a pic of the internals and it looks clean except a slight burnt section around the power or ground terminal connection to the board. Any ideas or thoughts? Is it worth the gamble? Does it sound like repair is even a possibility or is this failure irreversible? Thanks in advance guys.
