It all depends on how you measure the power doesn't it? Are we talking
of
power input, RMS output or peak music power?

In the days of the amp' mentioned manufacturers (and sellers) could
juggle with these figures all day long to come out with ridiculous
figures and an ignoramus customer would
often be shown the ac power input which due to the sheer inefficiencies
of the day
could be 3 times the RMS output figure. Peak music power could be
quoted as 3 times this again! Fun eh?
