hot dang your good!!
I took it out and simulation is same, no change.
how does the rest of that input look??
remember there are 4 duel pots, 4 - 47 K resistors, 4-1uf caps that all connect to the op3
just like the link **broken link removed**
been redoing the full schematic mixer section.
not sure if I want plugs w/ tails to connect to pots/circuit(hard wire each pot (5 wires to main board per pot) or make a circuit board just for the pots and run one pigtail from pot board to main board (3 wires total (grd, L,R))
the circuit board sound easy but it would need to be double sided.
