And also the key to having a cleaner signal. An amp that is over driven
(using AGC to control the drive power) or that is not well tuned will
generate lots of splatter, clicks, and other trash.
I don't know about the 3-500Zs used in the Centurion, but the key to
long life for the ceramic triodes used in the Titan is to keep the grid
current below its limits at all times. My objective is to keep the grid
current below half it's rated value, and my tubes last a LONG time. Grid
current is minimized when the amp is well tuned and not overdriven.
