Hum balance

8/22/2005 10:41 PM
Tracy	Hum balance I am building an amp with a full wave bridge power supply. I have recently discovered that my fixed bias supply needed to be capacitvely coupled. I used an Ampeg design, works great. now I am wondering about a hum balance pot. The ampeg amp shows a 100 ohm pot with the wiper connected to ground through a .047 cap. my question is how many watts should the pot be, and is the cap used to block DC volts?
