Your power supply's output is still noisy after the swap, or that filter cap has finally鼓ed and popped. This is the right fix: a 4.7 microfarad electrolytic rated to 63 VDC, RB (PC) mount, ready to slot straight into your board. It smooths the DC rail, tames ripple, and does the low-pass filtering job it was designed for. Polarised, so check the stripe before you solder. One part, one job, done
