Your PSU output's still jittery after the last repair. The cap you grabbed from the bin wasn't low-ESR, or it was the wrong value. This 220µF, 25VDC low-ESR electrolytic is built to handle 640 mA rms of ripple at 105°C with impedance capped at 0.13 Ω at 20°C. That's a tight, stable rail without the cap adding its own noise. Polarized, radial leads, standard pitch — it drops into the same footprint as the original. Solder, power up, and stop chasing phantoms
