Alright yeah it was definitely IC3 being bunk, new chip works great. I haven't ordered op-amps in about 2 years (I've been surviving off...

I literally just finished replacing the IC with a socket so I should have a number for you in just a moment!

Each of the vref bias resistors read 4.288v on the voltage divider side of the power supply, readings are taken after each point's...

Vref of 4.288v R2 3.917v R17 3.704v R21 4.251v R22 4.251v R23 .051v R24 4.262v R31 3.92v R23 being the obvious odd man out, it's on...
