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 of a personal hoard) so I guess one of them was gonna fail if I kept them jumbled around in a box of parts long enough. Performing as intended now. Anyone have...
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 respective biasing resistor****
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 the lower frequency voice of the two active eqs on the "high" control
I've built a Promethium in the past and it worked like a gem first try but I built another for a buddy and now I've got this bizarre octave up that sounds like the sort of full wave rectification you would get from a Green Ringer or a TB Octavia (I understand that they achieve their octaves in...
