I read some posts on the Power Supply forum about actively "filtering" out noise from power supplies. They referenced this site:

Has anyone tried to do something like this for Chip Amps??
Any ideas why it may/may not work??
TIA

If you're considering a 1 ohm series resistor, a simple RC made of the resistor and 10,000uF of capacitance is going to give you a few dBs better filtering, or even 2 ohms, or two stages. The series resistor may even relax ringing in the electrolytics, if there is any. Just a thought.
Yes, but this is more sucessful with an amp that has a more constant draw of current. It is often done with class A amps. You could make sure you had a large enough cap after the dropping resistor but that'd average out the drop which would be less at amp idle, and more under heavy use.ew said:could a rc filter be used to knock the voltage down by 2-4volts?
A regulator would be a more consistent way to burn some volts, if you can afford the volts.
