Re: Question to Carl
Not Carl here but I can help a tad here. The grid stoppers are located on the power tube sockets. Usually 1.5K in value. If you look at the power tube socket on a fender amp you'll see two resistors soldered across the socket. The top one is the screen resistor. Usually 470 ohms, and underneath that resistor you'll see the grid stopper, usually 1.5K in value.  
As for the explanation of what they do I'll provide you a link to Randall Aiken's excellent right up on Grid resistors - why are they used?  
Hope this helps some. I'm sure Carl will jump in any time.
