So that 1.08V is your DC offset, and you can't adjust that? Waaaay too high. Have you checked the power amp connectors to make sure they're plugged in right? Sounds silly, but back when I did an 1180DC, I managed to get the connectors offset by a pin so one of the pins wasn't getting power at all. Took me a while to figure out why my rebuilt 1180DC was only making 72 WPC.
