Filter Cap Hum at Russell Stinson blog

Filter Cap Hum. Filter caps have no effect on grounding hum, and shielding signal leads does. I've had excellent results and tangible improvements when replacing the original filter caps with nichicon gold tunes/super. No change in 60hz hum observed when comparing two cap configuration with one cap. .c1 and c2 are the filter caps. I put the dc blocker in the neutral line rather than the live, just to reduce the voltage difference between the capacitor cases and the well earthed metal box. The hum that remains with no input connected can be reduced by increasing the filter capacitor but adding a proper voltage regulator (linear or switched mode) would help. There are a zillion sources of hum, each one different from the next, and each with its own solution. Removing one fixed this issue. If your power supply doesn't have voltage. You can try increasing the values of those to reduce the hum.
