Vent: a guy at a swap meet in Toledo said you should always swap the caps, and I think that's just lazy bench work
He was selling NOS electrolytics out of a tackle box, and when I said I test before I pull he waved me off. "Just change em all, saves time." I get it for power supply filters on hot gear, but shotgunning every board is how you lift pads and miss the real fault. I fixed a Denon receiver two days ago with one open resistor. Swapping 30 caps would've took me hours and maybe wrecked the traces for nothing. So where's the line for you? Test first or always shotgun?
