Your power supply's humming. Your amp's adding a low buzz nobody asked for. Chances are the smoothing cap has drifted or dried out. This 470µF, 16VDC low-ESR electrolytic drops straight into the same footprint as the original and kills that ripple at the source. Polarized — mind the stripe. Radial leads on standard pitch, so it slots into your board without a rework session. Rated for 2,000–4,000 hours of load life at 105°C, which in practice means it's not the part you're chasing again next year. Grab the one you need. Solder it in. Move on
