Your supply's output is noisy and the 10µF slot needs a cap that doesn't leak half its stored energy back into the circuit. This Jaycar electrolytic is rated to 50VDC and 85°C, with leakage characteristics that sit close to a tantalum cap without the tantalum price tag. Polarized – positive terminal must always exceed negative. Use it for power supply filtering, input/output smoothing, or LPF stages. Drop it in, power up, ripple gone
