help me read this circuit? please?

[quincy]

what does it mean in this circuit when the wire just ends with a dark rectangle? is that ground?
i cant find that symbol anywhere.

 

[quincy]

oh, come on. the three of you who already read this could at least say something.

hi quincy,

Its just another symbol for ground, 0V ref for the +/-Vcc supplies.

Does that help?

 

[quincy]

yes! thank you! i just wanted to make sure it wasnt some other random thing that i didnt know about. Ive just never seen it that way before.

An error on the schematic causes Q5 to be shorted.
