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?

I disagree.

CF is very important in the circuit of the topology you described! Try bypassing the CF (without replacing it with a transformer)in your preamp's output circuit and you will see how important it is on how the preamp will sound and how it will perform driving the load.

Just my opinion....
