Clearly in need of something to do - I bought one of
those power/volt
etc measurement thingies and came up with this:

Mac Mini Computer 1.25 25W
Mac Mini Computer 1.25 Standby 2W
Mac Mini Computer 1.25 Off 1W
19" AOC LCD Monitor 35W
19" AOC LCD Monitor Standby 4W
Wireless Phone 1W
PC 3200 AMD 110W
PC 3200 AMD Standby/Off 5W
100W Valve Stereo Amplifier 170W
Pure Evoke Digital Radio 5W
Pure Evoke Digital Radio Standby 5W
70W Stereo Solid State Power Amplifier 25W

The curious thing about the SS amp is that it starts
at about 63W, then seems to settle down after a minute or
two at 25W. Volume at either of the amps wasn't high
- from zero up to need-to-raise-your-voice - but
consumption stayed about the same. Carry on ...

Have you a link to the site where you got it from ?

Hi Dave - it's:

http://www.maplin.co.uk/Module.aspx?...power&doy=26m4

item L61AQ

but I paid about 10 quid - they're on offer from time to
time. It seems to measure watts accurately, but the
display is rather dim and ironic that it uses 'up to'
20W.

Looks like a slightly brain dead version of a product we
have in the US called a "Kill-A-Watt". The US product
will integrate energy usage over time as well.

As will this - in what (haha) way is this one 'brain
dead'?

I thought you said it wouldn't compute watt-hours or some such.
