Fair enough, but where do I connect the two outputs. One is connected to the signal on the headphones (?), but what about the other? Presumably it wouldn't be labled as 'out' on the diag if it didn't do something!
TillEulenspiegel said:Really? I've never seen anything like it unless it was phantom power for ES headphones or mics. There's also a differential DC potential between the outs......like I said the circuit is a basic cap coupled amp , but I don't understand the DC element on the outs.
one to the live side of the headphones, the other to the ground side of the headphones

Couldn't you use DC blocking caps on the output?
