Hi
I was looking through the specs of a vintage amp and it says the power output is 25 watts RMS per channel and it qualifies this by adding the statement "Measured Pursuant To Federal Trade Commission Regulation Rule On Power Output Claims for Amplifiers"
This is of course an American standard and this is the first time I am seeing such a statement added in with the specification sheet of an amp.
But what I am wondering about is , is there any difference between how power output is measured as per American standards and how it is measured according to British standars. I have never seen any spec sheet of an amp saying the power output claims are as per Brtisih regulations.
