Ok, the first question is a really basic one that I'm 99% I know the answer to, but none the less.....
Say I have 18v rails. The power transistors at most only ever see a Vce of 18V right, not 36? (In a simplified sense. I realize they can't swing quite to the full rail voltage)
Now for some power output computations. Assuming a full power square wave output into 8 ohms, and the aforementioned 18 volt rails, would I be at that time putting out:
(18*18)/8 = 40.5
40.5/2 = 20.25 watts?
also, does computing r.m.s. with a square wave have any meaning? I would assume not.
With that said, r.m.s. is pretty much only correct with a sine wave right?
In short, is the stated r.m.s. wattage of an amp a sort of fudge since music is not sine waves? Or is there something more.
