    Dc coupled amplifiers. Where does the dc go?

    I’ve read a few posts on this. I know of has to do with the offset and the differential transistors but I’m still confused. I assume the positive and negative voltages bring the output to 0v dc but doesn’t that cancel the voltages used to power the output transistors? If it’s a dumb question...
