Recently finished the Kliche and when I plugged it in and powered it up it started squealing. If I moved enough stuff around it would go quiet and could very very faintly hear my guitar. Not quite sure where to start on this one. Any help would be appreciated.
Nothing is jumping out to me at first glance but it is hard to tell. Got a probe or a breadboard and an extra jack to make one? Definitely start with cleaning and reflowing everything though.
I figured it out i put LT1054 Charge pump in the TL072CP bag. I never checked and assumed i put the right op amp in as i grabbed the TL072CP bag. I was perplexed at why my voltage was double what the other guy had upon staring at the board i realized the OP amp number was not correct. Found the proper ones and it works like a charm
