A rectifier tube (diode) changes alternating current into little lumps of direct current. See

what does a Rectifier tube do?
I have an Air Tight Atm1 amp which uses 2 5ar4 Rectifier tubes. The manufacturer calls it Mullard Rectification. My question is what is Rectification? I ask becuase AirTight makes ATM3s which use the same tubes (EL34) but do not use 5ar4s for Rectification. Would that mean there is a different sound even though both amps use the same Output tube?
