Home Forums GuitarPCB Build Support BMP OPAMP oscillating (answered) Reply To: BMP OPAMP oscillating (answered)


Most anyone who has experienced oscillation in pedal builds should look for a bad solder joint somewhere. Short of using an audio probe simply re-flow all solder joints both on and off board including pots and jacks. They should be shiny and look like a tiny Hershey kiss. Beware of over heating.

Further help requires photos and voltages however I would certainly bet on a cold solder joint.
