Ahhhh, so there's no big capacitor across the +/-.
When I worked on old dumb terminals, we'd occasionally have a bad power supply (pre switching PS days). It was always the big capacitor across the 5V. Since they wouldn't let US techs do board-level repairs (some bean-counter determined it was cheaper to ship the thing halfway across the country instead of replacing a $3 cap), I'd write "LUMPY VOLTS" on the return tag and send it to the depot.
