Hi guys, wondered if i might be able to pick your brains on a problem superfuzz build. Basically its a pcb build from a good source, i can hear it working, just quietly, and when i pull out the psu it suddenly goes very loud before the sound disappears. Any ideas as to what may have gone wrong?
Thanks
Dave

Soldering on the DC adapter?

I dont think so, i have it hooked up to a test rig which i know for sure is fine, maybe I'll check again later though.
Cheers
