As you can see, we've all made our share of mistakes. I put an IC in
backwards but caught it in time ( before power was applied ). No need to
beat yourself up over it. The good news is if you follow Paul's excellent
instructions you have the coolest synth modules available and they all work
superbly. I did'nt have to troubleshoot any of the six I've built. (keeping
fingers crossed).
