I recently built a 842/10 amp that needed either 1600ohms or 3000ohms in the cathode. using a switch proved to be the best option. It also worked nicely as a tie point (solder lug) inside the amp. Using a 25W pot is good for experimenting, dialing in the best values, but not much for the final design.
