Those 2 scenarios make sense but if one tube tests at 100% and another tests at 75% and no shorts, they shouldn’t both produce the same voltage? I can’t see where there would be a difference.

Music is a dynamic load. Heavy bass passages pull more current. A weak tube will cause plate voltage to sag with high-current loads affecting the sound.
