Can someone confirm that the opamp is in the wrong direction in this picture, according to the supplied schematic?

Ignore the pictures

Trace pin 1 on the chip (with the dot) it should go to C3 +.

And yes the picture and schematic pic are different.
Normaly the electrolytics are marked + on the board...the board should be correct..looking at the picture on the schematic makes me think check/ trace the board and make sure it matches the schematic..


Yawn..Laters
