just wondering if there is a way to test the actually output of an amp. there HAS to be some kinda device or something used to rate the power output, but just how?

From another post...............set MM to A/C voltage....play some tunes and watch peak voltage....square this then divide that number by the impedance load. This gives a close idea.
