Tube Basics 101: What is a rectifier tube for?


In laymans terms please:

What is the function of a Rectifier tube (such as the 5AR4/GZ34 found in my tube preamp)?

Why/How would the Rectifier tube affect the sound created?

How would this differ from the function of a typtical Driver tube (such as a 6SN7, 12AX7, 12AU7)? Also, would a driver tube typically have more affect on the overall sound (i.e. Which tubes would you roll out first if you wanted to change the sound of your preamp?)

Also, what is a "Getter" tube?

Just went through this situtation myself! Brent jessee helped a great deal! Up graded to siemans 12at7 tubes from rca's- huge improvement! Than upgraded rec.and what it did was increase presence,depth,sound stage and gave a punch to the low end!it has to do with current.so the rec. Is an important part as to providing higher current to the pre. I liken it to the right pre and amp combination. Each sys is going to react diff.its trial and error.try diff. Rec. And see which one you like the best!this (to me )
falls into
More or less tweeking your sys. Assumeing pre,amp,and speakers work well together.brent explaint it better, but it still comes down to "what you like
I went thru 6 diff. Amps,7 pre's and 15 pair of speakers untill I hit on the present combo. And it was worth it!!the tubes power and rec. (Fine tuned) the sys. To exactly what I was looking (or listening for).Brent jessee was a great help, can't recommend him highly enough!
