IC1B is labeled wrong.Pin 5 is the Positive input and is normally grounded in this configuration,, It looks like it's + & - input labels are flipped. I can't read the label Numbers,, they both read 5 to me.Phil.

Pins 2 & 6 head to ground.You're saying they'd normally flip the positive the other way when using both halves of the 4558? I'll look when I'm in there in a few days to see how it's really wired.
