It does more than help. It completely eliminates the buzz. Check out the measurements I made on the Stoetkit amplifier, which uses a bridge rectifier using 1N4007 diodes followed with an RC hum filter. After installing 0.22uF caps across the diodes, the switching artifact was completely eliminated.
