Bench supply sagging under load

Placeholder log entry. Short, dated, and written the way a bench note actually gets written: one problem, whatever got measured, and where it was left.

Loaded the 12V rail to 3A and watched it settle at 11.2V. Ripple looked unremarkable on the scope, so the transformer is probably fine and the fault sits somewhere in the feedback path.

Next: pull the sense resistor and check it against the schematic value before ordering anything.
