Low-voltage rail is sagging under load and your 5V or 12V output isn't holding steady. A 100 microfarad cap at 16 volts is the standard smoothing stage for most hobby and small-project power supplies. RB mount, so it sits flat on the PCB and you don't need a standoff or wire jumper. Polarized — get the stripe right or you've got a very expensive smoke show. 170 mA ripple current covers typical linear regulator draws without thermal stress. Solder it in, power up, and your output stays clean
