People frequently talk that a higher loading has lower distortions but I do not thing that is has anything to do with distortions. The key in here is that harmonics that are changed with lording – higher loading get “shorter” harmonics, and less idle load has more “fatter” harmonics. My experiments with electromagnets suggested that they are a bit on the softer side then better perm magnets, therefore if I run electromagnets then I would most likely load the tube lighter with field-coils drivers.
