I've checked component values and inspected for solder bridges or melted caps. I scrubbed both sides of the board clean of flux. The only sub I made is an Op07 instead of the LM308, I left the 30pf compensation cap in because I read that it did no harm, could that be causing no sound? I checked voltages on the IC and they're all wrong +/-9V on pin 1&8, and around 8.6V on 2-3&6-7, 9V again on pin 4 and nothing on 5. Is there more investigation I can do with just a DMM or do I need a scope/function generator? Any help is appreciated, the Madbean forums are down.
