If you l...Right, the triangle represents an OP-amp. If you look at page 2 in my link (the LM833-n datasheet) there is a picture showing the internal layout of the IC. The +VCC/-VEE is for the supply voltage for the IC which is not marked on the pedal layout. The +IN/-IN is the +/- on the triangle in the layout. E.g. the LM833 has two OP-amps inside it (A and B). The half-circle on the IC indicates the orientation.Kafzillahttps://www.blogger.com/profile/13116693384992452308noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-62599653887553370632018-04-12T21:33:23.867+01:002018-04-12T21:33:23.867+01:00Thanks Kafzilla.
