Gonk,

Tried this before, and this is how I think I isolated it to the 990 Right output. However, I visited with Steve at Outlaw after posting this message, and he recommended I do a system reset, re-load the firware update, do another system reset, and see if this is the problem. He feels that it is usually software or firmware on this type of problem, and rarely ever actually a bad output on the 990. I haven't done this yet, but I will get to it this afternoon. Thanks for your post!
