Anyone or all,

What is the working definition of a "rectifier" and what is the mechanics surrounding the use of a tube in this process? In other words, what is being rectified when producing amplified sound???

The rectifier (tube or solid state) converts the incoming AC power from the power transformer to DC to provide power for the amplifier.

A simple definition is that the amp rectifier takes AC voltage from the wall and converts it to DC voltage...the DCV in amps can be as high as 450/500 volts,AC (alternating current) flows back and forth,DC (direct current) flows only one way and that is what the components in the amps use.

Rectifier is usually used to name a function that enter AC and produce output DC with diodes.
The principle of the "di-ode" (like tri-ode) is a 2 electr"odes" in vaccum, one is heat up creating a "cloud" of electrons that escape from the hot electrode but go back du to to atomic forces. I you apply a positive voltage between the cold and hot electrodes then you accelerate the electrons that can joint the cold electrode (positive current). But if the voltage is inverted then the electrons are push back to the hot electrode (no current).
Consequently only a positive voltage allows output current.
That's rectifying an AC by "cutting" the negative part of the voltage.
