More or less any consumer grade switch mode power supply! The Draytek in
question was a, can't remember the blinking number but was a rack
mounted jobby.

Had a TV the other day the caps after the rectifier where shot oddly
enough read fine on a PEEK Cap tester but a couple of new 105 deg ones
sorted that.

And for that matter any test gear of a certain age, power supply caps
change them they don't last forever!..
