Your power supply's humming again. That swollen or dried-out cap in the filter chain is why. This Jaycar 470µF at 25VDC slots straight into the input or output smoothing stage and kills the ripple before it reaches your board. Polarized – mind the polarity when you solder it in. Low ESR keeps heat down under load, so your supply stays quiet and stable. One part, one job, done
