Note the first comment.

There's an error on the schematic -- pin #3 on the first NE5532 does not connect to the junction of the 47 k and the 100 Ω -- it only connects to the two 47 k resistors.

		The comment is worded a bit cryptic, that joint should not be there, the wire should cross the wire coming from pin #2, not connect to it so that joint mark should not be there.
