Your power supply's output is humming, the board runs hot, and the old electrolytic cap has dried out. That's a 2200 µF smoothing job, and this Jaycar low-ESR unit handles it without the voltage ripple you're fighting right now. Polarised: positive terminal always reads higher than negative. Drop it in as an input or output filter, or as part of your LPF stage, and the ripple drops. 1900 mA rms ripple current at 105 °C / 100 kHz means it's rated for real load, not just a datasheet footnote. Impedance sits at 0.05 Ω max (20 °C, 100 kHz), so it stays stable under sustained draw. Radial leads on standard pitch make it a straight-through replacement in most through-hole boards. Add to cart and it's on its way from an Australian warehouse
