What makes an amp Class A, A/B etc,

I was wondering,

What makes an amp Class A, A/B and other designation, and do these ratings apply to Pre-Amps and Phono sections ?

Thanks for this and other comments to past queries here on the forum.

Best Regards

Thanks Mark

So Class A has the most power consumption and operates ineffeciently but carries the ? cleanest or least distorted? signal without feedback. or is that too simple.

Also is this related to feedback at all or is that another aspect of amp design.

I have also heard of class d amps.
Are there any references that explain these types of terms as well as push-pull, balanced-unbalanced, feedback and the like

It is a lot to fathom, an idiots guide to amplification theory is what I need !!
if you will!

Thanks again Mark
