100 microvolts of DC offset is spectacularly impressive particularly for a channel that I assume was operating at half the rated maximum power (700W) when this measurement was taken!



Just re-read my post and realized (again) that I need to pay more attention when I am typing. I meant to say that I assume the channel was playing at 700W (ie. getting warmed up) prior to turning off the source and taking the measurement.
