hey there, i have an old dod 585 delay with the mn3005 bbd thats having issues, im wondering if anyone can see what the issue might be with the voltages i took. so far i have  checked the polarity diode and replaced all of the old electro caps without any change in results. the sound is sort of a synthy ring mod with distortion added with the delay pot. ive been thinking about the madbean aqua project but i have to confirm the chips are ok before i can even consider the project so i'd like to know if these chips look okay. anyways heres the voltages, (except for the op amps, they look okay) if anybody can see any suspects, it'd be greatly appreciated!
