Watts are all created equal: class A, AB, tube SS, digital etc... Power ratings can or can't be precice and/or honest depending on manufacturer. There are quite a few power ratings that have to characterize an amplifier and part of them is partially derived of power supply capabilities along with output devices that are critically calculated for the large signal calculation and class of operation.

It has nothing to do with class of operation. 2.Any amp with no feedback will oscillate. A feedback is a-must in input and driving stages. 3.Class A allows to minimize the feedback at the output stage but presence is still helpfull and very often even neccessary.
