It wasnt too much work, about 5 mins each. I was hoping to get all these made this morning but since my local RS didnt have all the parts I figured I could make what I had. Any idea how much the chips are from mouser? I can make these for $3-4 each.
I have the manual here it says to use 6 resistors per module leaving the center pins open.
I would like to have a digital EQ, but this one has been working great for the last 8 years so I'll keep running it for now.
