Here in the US, full service hardware stores usually have a little 
Circuit Tester you plug into the 3-prong outlet to tell you how the 
outlet is wired (or miswired).  Anyone who has any e-music gear worth 
protecting should spend the money to get one.  I think they are under 
$5.00.

It won't get rid of your hum, but it will tell you if the circuit is 
wired correctly.

Mine is from Gardner Bender, Inc. Milwaukee WI 53209.  Using 3 lights 
(2 amber, 1 red), it shows the following conditions:
--open ground
--open neutral
--open hot
--hot/ground reverse
--hot/neuttral reverse
--correct

Mine is yellow; evidently they are now red.  Looks like list is now 
$5.49.

If you want one, try a hardware store.

Hope this helps.

PS:  If you attempt to rewire an outlet (or convert froma two prong 
socket to a three prong socket), please make sure the circuit is off 
first!!!  (The tester is also good for that--much handier than 
carting around a light or powering up your rig.)
