Well now. Perry asked me if I had checked the fuses. I had at that time. Now after a many more attempts at this thing I re checked the fuses because as I said below, I was going to start all over. I checked them again. Low and behold, Left channel - rail fuse was blown. I do not have any replacements for this size so I took the good ones from the right and fired it up left channel only. DC offset looks good initially and if anything the bias is running a bit high.
