Thanks, all. I had to put this on the back burner for now, as we lost three people at my job (I'm buried, working weekends) and I just found out my mother has pancreatic cancer. I also emailed Jeff Rowland, and they (Jeff himself?) told me what to look for to help them analyze what is wrong. With all that's going on, I haven't had time to do that. I have a 3 day weekend this weekend, and while I'll work one of those days, I plan to take two days off. So, I might be able to open the amp and see what's up. I have to do it this weekend, as once my mother starts chemo, I think I'll be helping her.
