power supply hum problem

i have a 0-600vdc 0-200mA solid state power supply, hums when i raise voltage with no load to 250vdc & above and hums noticeably with a load. I replaced can electrolytics with new computer grade, i had to replace with larger values, i.e. 300uF were replaced with 470uF same WVDC. Any ideas?
