The answer to that could fill a book. Or at least a chapter or two of a book. A few days spend studying the Radiotron Designer's Handbook will help a lot- this is a complex issue with a lot of variables.

Or... you can just go with the recommendations of the tube manufacturer. Most data sheets for power tubes give suggestions for load, bias, power, and distortion.

If you don't have the tube's data, you'll probably find it here:
