Rectifier tubes help convert AC current to DC current, playing a pivotal role in helping supply power to other tubes in the amp. Though the guitar signal never actually passes through the tube, different rectifiers can have an impact on how your amp sounds. Rectifiers can influence the "touch", "feel", and sustain of your amp - usually called the "sag" effect.
