    I just thought I would ask as the Marshall book I have says 30w
    and most people say it's 45 as the badge implies.
    What's the REAL truth?

    It's about 33 watts (British - that is, accurate). It's a Goldilocks amp volume wise, just right.

    Best, Pete.

    Are those Imperial Watts? Watts the difference between Brit and Yank here?

    ^Watts are the same, he means that Brits tend to measure watts accurately while we....don't.

    When I did classroom training on electronics I used to mention that a certain device was 100Watts. But because it was made in England it was rated in British Watts which are more powerful. If the class didn't laugh I knew I was in trouble. :)

    The re-issue JTM45 amps are 30 watts output, and this is consistent. Originals tended to vary in output from 28 to 35 watts, mainly due to variances in components used and tolerances of the transformers.
